Umqolo plastic ekhaya.

Plastics Manje ezivamile ekuphileni kwethu kwansuku zonke. Plastic ekhiqizwa ezihlukahlukene izimoto, izakhiwo, zikagesi eziphezu kwamakhabethe kanye ifenisha, izitsha nokunye okuningi. Ngokuvamile handyman plastic ekhaya isetshenziswa njengophawu impahla eluhlaza ukukhiqiza ezihlukahlukene izinto ewusizo.

Zonke amapulasitiki zisetshenziselwa ukukhiqiza imikhiqizo yasendlini, ngamaqembu amabili: Thermoplastic futhi thermosetting.

Thermosets libhekene nobulukhuni esiphezulu futhi plasticity ubuncane evumela ukuthi ukuba hhayi ancibilike noma ukuthambisa lapho sishiswa ngakho.

Lapho ukufuthelana lokushisa thermoplastics ethile, ukugcwala amanzi, kodwa uma izinga lokushisa lehla futhi ziqine. Le mpahla kwenza thermoplastics umjovo udini ekhaya futhi wenze imininingwane.

Kuyini ukubunjwa amapulasitiki? Indlela plastic yenziwa ekhaya?

plastic Homemade kukwazi ukwakhiwa ngendlela elandelayo. Kumele kube kahle okuxubile sawdust esihle futhi Magnesite ku isilinganiso 2: 1, uthele isixazululo ingxube magnesium 0.1% chloride ugovuze ukuze bathole isimo pasty. Ukuze uthole imininingwane amapulasitiki ezinjalo zisetshenziswa ngendlela eyisisekelo - umjovo udini ekhaya shape. Phakathi solidification, plastic iyoba namandla ngempela high ne ukuhambisana ezinhle ukwelashwa, okungukuthi, akunzima ukuba sokuprakthiza, isaha, ukusingatha ithuluzi olwalwenza noma ifayela.

Kungenzeka ukukhiqiza plastic ngenye indlela. Kuyadingeka ukuba uhlanganise esihle ukhuni uthuli talc phansi isilinganiso 5: 2 futhi uthele glue olungiselelwe kusengaphambili joiner sika. I ingcina kufanele ibe bomsebenzi ukhilimu obukhulu. Ingxube kwaphumela kwaba isiyaluyalu ezidingekayo ukuze bathole isimo pasty. Uyacabangela ukwethula ingxube 2.1 ngenxenye okuningi noma umanyolo alum, ukuhlinzeka isivikelo isikhunta namafutha omiswe zemvelo, inikeza ductility owengeziwe. uma uthanda, plastic kungenziwa ezinemibala. Ukuze lokhu kumele kungezwe ku ukwakheka kwe-amapulasitiki aniline ukudaya umbala oyifunayo. Ukuze uthole imininingwane echaza indlela yokukhiqiza - ekubunjweni plastic ekhaya shape. Ukuze kwandiswe amandla ka amapulasitiki e ingxube ngesikhathi enza esikhundleni glue wathela nitro uqweqwe noma nitrocellulose lacquer. Yekuchumana nazo eyenziwe ekubunjweni.

izici Lihle plastic, okuyinto okulungiselelwe kusukela izingxenye ezilandelayo: i-glue iphepha isisindo dry / ezomile yombazi / ukugaya wokulinganisa / glycerol / Ethanol / ocher esihle ezomile, axutshwa ngokuvumelana izingxenye ngesisindo sezinti 5/28/60 / 2.5 / 3, 5/1.

It is kakhulu ochotshoziwe isisindo dry leliphepha uthele buhlanjululwe glue joiner sika. Phakathi dilution kufanele kancane kancane iqondiswa glycerol, wokulinganisa, ocher kanye notshwala, namanje ukuwaxuba. Izingxenye zalo ingxube ezisetshenziswa njengeziwusizo ukubumba amapulasitiki ekhaya. Umkhiqizo anemibala, uma ingezwe ku ingxube aniline.

amapulasitiki Phenol-formaldehyde nazo akunzima ukupheka ekhaya. Kumelwe siwubheke njengobaluleke crystalline (phenol) hydroxybenzene noma analogs kanye isixazululo aqueous of 40% formalin. Kanzulu carbolic acid uyakwazi ngokugcwele ozothatha indawo phenol. Kuyadingeka ukuxuba phenol crystalline (20g) nge formalin (30 g), unezela kanzulu hydrochloric acid (30 amathonsi). Kunalokho, kungenzeka ukuthi phenol esetshenziswa carbolic acid (40ml). Ingxube kufanele angesabi ashisise futhi ubilise, futhi iyoba ukuvumelana kwezincwadi lwengilazi futhi viscous. Ungqimba umphumela uthele isikhunta 30 amaminithi ngemva kwalokho ingxube kwaba efomini emanzini abilayo imizuzu 10-15. Khona-ke ungakwazi ukususa umkhiqizo kusuka isikhunta. etholwe resin Ngakho - kuyinto plastic thermosetting nge nombala obomvu, a ubulukhuni namandla. Kusukela kungenzeka ukukhiqiza izingxenye enzelwe ukuthi babe sesimeni imithwalo abalulekile.
