Kanye eziningi izinto newfangled Izingxube futhi kuseyingxenye ethandwa kakhulu. ukuhlobana babo obuyimfihlo ilula: okokusebenza etholakalayo, kulula ukusebenza, okuhlala isikhathi eside futhi ukonga.

Plasticizers ekwakheni

Ukuze uthuthukise izinga ngokhonkolo izixazululo plasticizers kunezelwa - inhlanganisela chemical. Umsebenti wabo - ukunciphisa okuqukethwe amanzi futhi ekulinganiseni isixazululo, kanjalo ngcono izakhiwo zalo. Abakhi plasticizer for ukhonkolo ngezandla zabo inqubo ukulungiselela yesixazululo. Abakhi ukwakhiwa okunjalo kungaba kokubili Izigayo zethu angaphandle, ngoba value abo ziyahlukahluka, kodwa sonke etholakala emakethe evulekile.

Lapho ukwakhiwa emikhulu, njengoba umthetho, wathenga izixazululo ngomumo eyenziwe. isingeniso engeziwe ye plasticizers, bona angadingi, le izingoma kunezelwa ngesikhathi senqubo yokukhiqiza. Ngokuvamile kuyabiza futhi eliphezulu plasticizers for ukhonkolo, amanani abo, yebo, kuthinte inani, kodwa izinto ezinjalo iyophinde kube kuhle. Desire abakhiqizi ukuqinisekisa izinga ukwakhiwa yesixazululo ulungisiswa ngokugcwele, umncintiswano namuhla kuphezulu kakhulu.

Lapho ukwakhiwa yangasese, uma izindleko ukhonkolo ziphansi, ukuthenga isixazululo ngomumo eyenziwe - ke ezibizayo futhi ngaso sonke isikhathi esizwakalako. Ezimweni ezinjalo, izingoma ezisetshenziswa noma uthenge noma plasticizer okuzenzela sengezwe ukhonkolo. Izandla zakhe enza kube lula ngokwanele, ngisho lokhu kuzoba kakhulu ukulondoloza ku ukuthengwa izinto.

imisebenzi plasticizers

Umgomo oyinhloko - ekulinganiseni ngenxa aphansi amanzi ukusetshenziswa futhi ngcono plasticity yesixazululo. Ngo ukwakheka plasticizer ifaka izinto ukuthi uxhumana nezinye izinto futhi obumba nokunwebeka ingxube ngezinhlamvu ezihlelwa ngesandla. Lokhu kusiza sokukhwelana kangcono nge isixazululo of base kanye nezinye izingxenye, ngaleyo ndlela kwande amandla futhi kwabantu ukhonkolo.

Isixazululo akusho ukwehlukanisa ku ephambili yayo izingxenye namanzi. isikhathi sokuphila kwalo inyuka ngenxa yokuthi ukuthi mass uyayibamba kancane. Kuba kunokwenzeka ukulungisa amaphutha uzibophezele ngokuthulula noma ukuqeda izakhiwo.

Isendlalelo bome nombala, ngakhoke nesenzakalo ukuqhekeka lincishisiwe. Ukumelana Ukwandiswa ukuze lokushisa ukweqisa.

Plasticizers enkulu ekwakhekeni

Ngaphezu ukusetshenziswa wokwakha noma ukuthelwa usimende izigqulo zinengxenye ukukhiqizwa zokwakha. Lena imikhiqizo ehlukene ukhonkolo, izitini zikakhonkolo, ezibuye, ukhonkolo kanye nabanye. Ekukhiqizeni kwabo ukusetshenziswa plasticizers futhi zibalulekile. Ubuchwepheshe ukukhiqizwa kudinga ukunamathela ezindinganisweni ezithile kwekhwalithi efaneleka kakhulu ephephile impahla. Ngakho, bonke plasticizers esetshenziswa, admixtures ukhonkolo kanye nezinye izingxenye kufanele athobele:

- uzinze amakhemikhali;

- ukuqukatha izakhi ezinobuthi;

- ungafaki compounds oluyingozi;

- ukubola ezingeni lokushisa ngaphezu kwezinga lokushisa ukwelashwa.

Kanjani ukwenza plasticizer kakhulu

Sekuyisikhathi eside sokwazi kanye namasu isakhiwo amakhosi wathola inguqulo ye kanjani ukwenza plasticizer for ukhonkolo ngezandla zabo, ngaphandle kokuba ukuthenga Izingxube ekhethekile. Lokhu samuntu kuyinto ukonga futhi ngokuphelele imvelo ephephile. imfihlo yakhe ilula: e inqubo ukulungiselela yesixazululo yengezwe lime noma yokuwasha izingoma. Lokhu kungaba noma yini: insipho insipho liquid, amashampu noma yokugeza izitsha yokuwasha. plasticizers okunjalo ukhonkolo, okuyinto shibhile klomelo, ingafinyelela miphumela emihle kakhulu, hhayi ivumele Uchwepheshe udade yayo emadolobheni. Isixazululo uzobe wabeka kalula futhi uyonikeza surface iyunifomu futhi abushelelezi. Quality lithuthukile ngokuphawulekayo, ukwanda kwabantu namandla kwesakhiwo. Ukwengeza izingxenye lelula uyogwema izinkinga eziningi nezixazululo ukhonkolo.

Technique nokunonophala izixazululo nge yokuwasha

Uma ufuna ukwenza plasticiser for ukhonkolo ngezandla zabo, kuyasiza ukulalela iseluleko onekhono ukwakhiwa sezingcweti.

Nazi izincomo main:

- insipho Dry (izinsipho) kufanele ukungezwa isixazululo, ngemva Ukuqedwa emanzini.

- ukwengeza imali kusese nesikhathi kwinqubo. Lokhu kuzokuvumela ukuba encapsulate kangcono ezengeziwe ukhonkolo admixtures (ukhonkolo block, njll), futhi ngezithukuthuku yezingxenye ngeke sixhumane kangcono nomunye.

- ngezabelo ngabanye kakhulu uhlobo ukhonkolo ngamunye. Kodwa ngokuvamile, le yokuwasha liquid ungeze ngesilinganiso 1 inkomishi isaka kasimende ngayinye.

- Setting isikhathi lesi sisombululo kuzokhulisa amahora amathathu.

- Zama ukusebenzisa amathuluzi unganikezi i yinsada kephunkephu. Uma kungenjalo, uzodinga ukulinda kuze kube Foam luhlala, bese kuphela ukufeza umsebenzi.

Ukungeza lime

Solutions nge okuqukethwe lime avame ukusetshenziswa ezindaweni umswakama. Badlala indima ungangenisi amanzi, kusetshenziswe engxenyeni engezansi noma udonga lwangaphandle lwesakhiwo, okuyinto ivame ukubhekana umswakama. Ngokuyisisekelo isisekelo engaphansi endlini.

Lime ukhonza njengelungu plasticizer, ukwenza ngcono ikhwalithi, ukuqina kanye ukumelana lokushisa ekushiseni amakhaza. Isixazululo kuba pliable, kalula uhlezi phezu evele mpo, emva omiswe, ingeyona grid imifantu. Lime - material yemvelo, futhi okungezona ezinobuthi, uzosebenza njengenhloko isithiyo sokuthuthukiswa ukhunta ezindongeni nezinye izinkathazo. lime izindleko incane, kodwa umphumela bayowuthokozela nge.

Kanjani ukuze ungeze lime ikhambi

Inani lime yethulwa ngamunye ngamunye izixazululo, kuncike injongo yawo. Isilinganiso zingahluka kusuka 1 kuya 1 (I-Interiors) 1 kuya ku-6 (I-mbumbulu).

Ngaphambi kokwenza ikhambi lime ukuncibilikisa emanzini. Nakuba lime wafaka, ukulungiselela ingxube dry yesihlabathi usimende nodaka kuphela ke kufanele injected. Ukuze sisebenze izinto ezinjalo kuyadingeka ukugqoka amagilavu, ngaphandle kwalokho wena kungalimaza isikhumba.

nezinye izithasiselo

Kanye plasticizers nezinye izithasiselo khona ukhonkolo. Bavumela ukuthi usethe kudingekile ezimweni ezithile, property izixazululo, iqhakambisa futhi okwenza kube lula ukusebenza nabo.

- kunciphisa isikhathi setting (booster). Ziyakwazi esisemqoka lapho besebenza nobusika noma ezindaweni ezibandayo e. Kwenzeka ukuthi izikhathi ukwakhiwa kwezakhiwo eziyinkimbinkimbi kuthatha isikhathi iphele izinto ngazinye, futhi lokhu kukwenza ungakwazi kakhulu umsebenzi. Ngezikhathi ezinjalo, zikwenze zimane Irreplaceable.

- Kukhulisa ubude lukhuni (retarders). Plasticizers akuyona njalo wakwazi ukubhekana kangcono nale imisebenzi, nangaphansi kwezimo ezinjalo, i-course ithatha ngaphezulu wezikhali esindayo - vodoponiziteli. Zisetshenziswa ezimweni lapho kuyadingeka ukuthutha izixazululo ngomumo eyenziwe ibanga elide.

- Air entraining izingoma. isixazululo ayegcwele air Bubbles. Sidinga ukwandisa frost ukumelana naso futhi kwenze ukumelana namanzi. Asetshenziswa izixazululo nge ongaphakeme usimende okuqukethwe.

- emelana nokubanda enhlanzini yasezindaweni. Vele iyadingeka uma ezisebenza ezindaweni ezinezinga lokushisa ongaphakeme ukuba -15 degrees. Isixazululo hhayi kuphela ayigongobali futhi ivumela umsebenzi phambi, kodwa futhi osemanzi ezinhle futhi has ukuqina kakhulu. ukwakhiwa okunjalo uvumele ukwakhiwa unyaka wonke, ngaphandle kokuphazamiseka for the nobusika.

izithasiselo ezinjalo othengwe kusukela umakhi kanye nomthelela omuhle ikhwalithi kanye nokusebenza izinto. Play zabo cishe akunakwenzeka.

Sahlulela

Sesihlole ongakhetha ezimbalwa ukuthi kwandzisa wokwakha izixazululo ukuze sithuthukise izakhiwo zabo. Esimweni lapho ukwakhiwa sokuprakthiza ezincane, kungenzeka ukuba usebenzise lezi amaqhinga kancane izinjongo zabo. Izindleko kuyoba cishe zero, futhi umphumela uba isiqiniseko ukujabulisa.

Uma ungenalo uthemba iseluleko yalolu hlobo, ungahlala ukuthenga ngomumo-plasticiser for ukhonkolo. Iziyalezo ngamunye wabo uyothwala izincomo ecacile mayelana nendlela efanele wengeze indlela yokwakheka isixazululo bese umphumela efanele.
