Ukwenza isikhunta ngamatshe yokufakelwa ngezandla zabo: izinto ubuchwepheshe

Kuze kube muva nje, i-abami evele ngaphakathi nangaphandle izakhiwo ezisetshenziselwa itshe kuphela zemvelo. Ngokwemvelo, umhlobiso ezinjalo zibiza leyo nto ababengenamandla okukuthola kuwo wonke umuntu. Njengoba sekunama-emakethe ukwakhiwa zamatshe yokufakelwa bawahlobise ekhaya lakho yezimanga. Uqinile, engabizi, ongaboni akahlukile material yemvelo, kodwa okubaluleke kakhulu, ungenza ngokwakho.

Kulesi sihloko sizoxoxa indlela yokwenza ifomu zamatshe yokufakelwa ngezandla zabo. Siphinde sibheke lokho izinto singasetshenziswa lapha, futhi yiziphi izici zabo. Kodwa okokuqala, ake sibone, ukuthi siyitshe ezenziwe umuntu.

itshe yokufakelwa

zokwakha Natural bezilokhu zibiza. Lena ngokuyinhloko ngenxa ukukhiqizwa nokuthengiswa kwazo zokuthutha. abathengisi engumthengisi e zokwakha olulodwa axazulula inkinga ngokufaka esikhundleni amasampula idwala ezilinganayo ngobukhulu ukuthungwa, abenziwe izigqulo.

itshe Artificial okulungiselelwe ngokugcwalisa amafomu ezithile izixazululo esekelwe Gypsum noma usimende. amasampula eqandisiwe kapende sokuwunikeza umbala impahla yemvelo. Izakhiwo itshe yokufakelwa akuyona phansi kunabaphostoli zemvelo, futhi kwezinye izimo ngisho okudlula kuso. Futhi believe me, ukuze uwahlukanise zibukeke ngokuvamile abakwazi ngisho okhokhelwayo.

efomini isimangalo

Ukwenza itshe yokufakelwa iqala ekulungiseleleni lokuhlelekile kwetinhlobo letikhetsekile (matrices), lapho ikhambi is kamuva wathela nsuku ezithile. Badinga ukunikeza ubukhulu esizayo isampula ukuthungwa ngezinto zemvelo.

Amafomu ukwenziwa yokufakelwa itshe kumele:

• babe high amandla ngemishini;
• okuhle nemihuzuko ukumelana;
• ukumelana kuhlasela chemical izinto ezithile lichaza ekwakheni ikhambi.

Okwenza ifomu

In imvelo ekhaya amafomu zingenziwa:

• izinkuni;
• abicah;
• polyurethane.

On ukudayiswa kukhona matrices plastic, injoloba kanye polyurethane ezivamile. Cabanga emihle nemibi ngamunye lezi zinhlobo zezindwangu.

amafomu lokhuni

Ukwenza isikhunta ngamatshe yokufakelwa ngezandla emthini - hhayi ukhetho best. Uhlaka ababebuthene ngokhuni-matrix amabhodi okuyinto ungqongqoze simise ezithile. I-matrix phansi nalo ekhiqizwa kusuka ebhodini noma fiberboard. Ngokwemvelo, futhi zazo ezimise geometry yokukhuluma akukwazi lapha.

Ukwaluka edingekayo kufinyelelwa noma ngokusebenzisa ekhethekile Embossed plastic substrate, noma enye ngokusebenzisa phansi njengoba amabhodi obudala sebuningini zamehlo.

Izinzuzo amafomu sokhuni:

• eziphansi;
• lula ukukhiqiza.

Okumbi amafomu sokhuni:

• yobunzima ezimbi;
• ukuphila yizenzo;
• ukungakwazi ukwenza izihloko okwenyanga.

Silicone isikhunta

Silicone isikhunta ngamatshe lokwenziwa kuyaqina enkulu. Lokhu kuvumela esheshayo awahluphi ukususa umkhiqizo osuphelile kusukela matrix. Ukuze kukhiqizwe izinhlobo esetshenziswa enkulu viscosity abicah.

Izinzuzo abicah isikhunta:

• kuyaqina okusezingeni eliphezulu;
• enhle njengoba oluthile Gypsum;
• amandla eqine kakhulu;
• akubizi akhiqize kwawena.

Nemibi abicah isikhunta:

• ongaphakeme chemical ukumelana;
• kumiswa emoyeni abagcwele enkulu ekwakhekeni matrix, lapho kungase obungefani.

Ungaluthola kuphi abicah?

Silicone isikhunta ngamatshe eyenziwa kusukela abicah, okuyinto manje ngokukhululekile ithengwa ezitolo DIY. Bayidayise kit ehlanganisa abicah ketshezi futhi hardener ngokushintsha lokuhlushwa ezingasetshenziswa ulungise kwabantu impahla okuholela. Izindleko abicah ezitolo iqala nezinkulungwane ruble kilogram per, okuzokwenza uyavuma, hhayi ukuze ezishibhile, kodwa uma ifomu sitholwa, kuyoba ukufeza kathathu yayo.

Kungenzeka ukuba ugcine kancane, futhi uma ukulungiselela abicah ngokuzimele Silicon dioxide (amanzi ingilazi) kanye hardener acid noma utshwala evamile. Okunjalo abicah, ngokuqinisekile ngeke kuhluke izinga ekhethekile, Nokho, ezimweni ezimbi kakhulu, kungase kusetshenziswe okwenza ukuma. Kufanele kuqashelwe ukuthi ikhambi kusekelwe waterglass sikhula ngokushesha, ngakho wonke umsebenzi kumele wenziwe ngokushesha okukhulu.

Amafomu polyurethane

Ukwenza isikhunta ngamatshe yokufakelwa ngezandla aphume polyurethane - inketho ezivamile futhi engabizi. Polyurethane has zonke izakhiwo ezidingekayo ukudala matrix zazivuma futhi iqine eziyohlala ngaphezu konyaka owodwa. Izimfanelo zakhe engcono:

• okusezingeni eliphezulu ukuzinza ntathu;
• ukuzinza;
• chemical ukumelana amafutha, izihlanzi, acid;
• ingilazi ongaphakeme lokushisa shintsho;
• inertia ongaphakeme;
• okusezingeni eliphezulu nemihuzuko ukumelana.

Uma eqhathaniswa abicah, polyurethane ketshezi uwina futhi ngenxa fluidity okusezingeni eliphezulu. Lokhu kukuvumela nokuzala kakhulu ngokunembile amancanyana kancane amaphethini textural ukuthi bukhona zemvelo evele itshe.

Kuyini polyurethane?

Polyurethane - okokusebenza polymer sakhiwa polyol futhi isocyanate. Ukushintshashintsha isilinganiso kulezi zingxenye, ungathola kanzima, elithambile, nezimo, noma ngisho Foam. Lokhu kwenza kube jikelele ngokuphelele ngezinhloso zethu. Isikhunta for usimende, isibonelo, kungcono ukwenza polyurethane elithambile, usimende kuyinto isakhiwo esifanelekela elukhuni into. Ngokwesilinganiso, polyurethane isikhunta esikwazi ukumelana 1500-2000 Castings, futhi eliphezulu ifektri-matrix zingamelana kuze kufinyelele ayizinkulungwane 4-5. Izinqubo ezinjalo.

Thenga Polyurethane kungaba ezitolo DIY. Liphinde okuthengiswa ikhithi ehlanganisa izingxenye ezimbili: uquqaba ukusebenza futhi hardener. Inani amakhilogramu polyurethane ngamunye ruble 700-1000.

Yini ngidinga ngaphezulu?

Umbuzo olandelayo - indlela yokwenza ifomu, nokuthi kudingeka, ngaphezu ezibonakalayo? Okokuqala sidinga ukuthola ifomu master, okusho itshe isampula, okuyinto singathanda ukwenza. Futhi-ke, hhayi elilodwa. Ngokuvamile, ukukhiqizwa kwanoma isikhunta ngamatshe yokufakelwa ngezandla kusho ethela amasampula umthombo ngaphezulu. Master amafomu kungenzeka emihlanu noma eyishumi, kuye ngobukhulu nangamandla endaweni uzimele.

Amasampula angathengwa emakethe noma okufanayo hardware esitolo, futhi, kwelinye-matrix zingafakwa amatshe tabobunjwa kanye indlela yokwenza.

Okulandelayo, iya le formwork, ngakho indlela yokwenza isimo esigcawini itshe kungenziwa kuphela ukuyisebenzisa. Uhlaka engcono wenza kusukela chipboard laminated noma MDF. Siqukethe izindonga ezine, ukuphakama kokweqa iphuzu elingenhla ngobukhulu master isikhunta okungenani ngamasentimitha ambalwa. Phansi bezinhlamvu zingenziwa kusuka DVM noma kusukela chipboard efanayo laminated. Uhlaka design uya nezikulufi self-evunyelwe. Uma umphumela obandayo phakathi kwezindonga formwork kwakheka igebe ugcwalise kubo sealant acrylic.

Lapho indaba for ukuma amasampula amatshe ukuze ithengwe, kanye formwork libuthene, ungakwazi uqhubekele womshini matrix.

Bopha ifomu master

Indawo ohlakeni akha ngomala master side up ukuze ibanga hhayi engaphansi isentimitha therebetween. Manje, ngokusebenzisa esiku abicah isakhiwo uvikelekile ngamunye wabo, okubangela amaconsi ambalwa phansi isampuli. Phakathi phansi formwork namafomu master akufanele abe izimbotshana. Kungenjalo, abicah noma polyurethane ukugcwalisa kubo, futhi amasampula ngeke ukususa.

Ukwenza isikhunta ngamatshe yokufakelwa ngezandla

Ukuze-matrix ine geometry lesifanele, qiniseka ukuthi ngaphambi bathele formwork ingafakwa phezu flat. Lokhu, isibonelo, kungaba ithebula noma ngisho phansi flat.

Manje siya ukulungiswa indaba for matrix. Ukukhiqizwa abicah amafomu i itshe yokufakelwa (noma polyurethane) iqala ukuxuba yezingxenye. Lokhu kumele kwenziwe ngokuqinile ukunamathela olinganise ecacisiwe kuleli bhukwana. Noma yiluphi ushintsho kuzoholela yokuthi ifomu kuyoba noma Friend too, noma, Ngakolunye uhlangothi, lingazenzi zibe lukhuni. Kuhlangana yezingxenye Kwenziwa usebenzisa spatula emincane noma mixer ezivamile. Govuza ikhambi, musa ukusheshe uligcwalise ku shuttering. Ake ummise imizuzu embalwa Bubbles emoyeni isikhathi avuke kwamanzi. Ukuze le nqubo kwaba ngokushesha, amandla kungenziwa ukufuthelana nge isixazululo of a hairdryer.

Nakuba Bubbles emoyeni zitholakala, usebenzisa ibhulashi ukudaywa amatshe gcoba-amasampula, kanye ebusweni kokungenzi lutho phansi futhi ezisemaceleni uhlukanisa Ukwakheka ukwakha kalula uhlukane formwork. I isihlukanisi ingasetshenziswa ezivamile uwoyela motor, kodwa noma kunjalo hhayi abaqhuba. Gcoba ebusweni Kunconywa ngongqimba eziningana kuya ebusweni ukungena nakwamanye amazwe itshe kungase bondliwe ngamafutha. Uma loku kungentiwa, abicah noma polyurethane ukungena ezimbotsheni, okuholela ebusweni isikhunta bebengaba ukukhubazeka ohambelana.

Lapho usukwenzile lokhu, le formwork yokugcwalisa ngokulinganayo abicah noma isixazululo polyurethane njengoba ifomu master engamboziwe nge ungqimba kungekho ohlabayo kweyodwa isentimitha. Shiya ukuma esizayo yokuzigxilisa azungeza ngosuku. Kungcono uma solidification kuyokwenzeka ezingeni lokushisa phakathi +20 ° C.

Thina ukuhlola imiphumela umsebenzi wabo

kungenziwa Ekupheleni ifomu usuku asuswe formwork. Kwenze kangcono, ngemva kokuqeda uzimele. Ngakho-ke ngeke kube lula ukuhlukanisa matrix futhi kusukela izindonga kanye nemithi yayo namatshe. Uma ifomu washaya ezinye izindawo kakhulu Friend, ungamumbi ngayo zokubhala ummese. Ukwehlukanisa-matrix, uyivule surface ukusebenza, bese uvumele ukuze ome amahora ambalwa. Ngemva bayiqede isilonda ngendwangu ehlanzekile ngaphandle nengcindezi enamandla.

I-matrix yokuqala kungase yebo kwenzeke nonideal. Kodwa ungakhathazeki kakhulu, ngoba isipiliyoni - kuyofika isikhathi, futhi ukukhiqiza isamba elanele itshe yokufakelwa, ungadinga okungenani ezinhlanu la mafomu.
