Amatshe okufakelwa asetshenziswa kakhulu kumklamo wanamuhla. Zihlobisa kokubili izindonga zangaphandle zendlu , nokuhlobisa kwangaphakathi kwamakamelo. Itshe lokulingisa lithenda elihle kakhulu futhi lisetshenziswe ngezitayela ezehlukene lapho lihlobisa ingaphakathi nangaphandle. Futhi wayazi ukuthi itshe elinjalo lingenziwa ngokwayo usebenzisa amafomu akhethekile? Ziyi-plastiki, ibumbwe, i-polyurethane ne-silicone. Ngayinye yalezi zinto zinezici okudingeka uzicabangele uma uthenga. Ngakho-ke, ake sithole ukuthi yiziphi izinkuni ezinamacilisi ezenziwe ngetshe lokufakelwa.
Izinzuzo kanye nokungahleki kwezinto ezibunjiwe ze-silicone ngamatshe okuhlobisa
Njengoba kuyaziwa, ekwakhiweni kwetshe lokufakelwa ngokuvamile kusetshenziswa ukhonkolo olubombala. Ngokungafani ne-polyurethane, ukubunjwa kwe-silicone akulona okunqabile kakhulu kwesikhala se-alkali esinobudlova isixazululo sikhonkolo, futhi lokhu kuyingozi enkulu. Amafomu anjalo abhujiswa masinyane ngokusetshenziswa okunamandla. I-Gypsum ayiyona enobudlova njengokhonkolo, kodwa lapho ihlangana no-abicucu, inika umphumela ongajabulisayo wezingqimba ezivela ngakwesokunxele komkhiqizo. Futhi ukwehluleka okwesithathu kwe-silicone eyakhiwe yizindleko eziphansi: ama-silicone okubunjwa ngokwenza amatshe okufakelwa ayabiza kakhulu kunamapulasitiki.
Ngokuqondene nezinzuzo, i-silicone isagcina kakhulu kune-plastic noma ipulasitiki. Ngaphezu kwalokho, ihambisa ukukhululeka ngokucacile, okubalulekile lapho uzama ukwenza ubuso ngaphansi kwetshe ngosizo lwe-molds. Kubo, ukuguqulwa kwe-shrinkage akuyona into eyingqayizivele, ngoba izinto ezingabhekene nazo zithandeka kakhulu futhi zithobekile. Kuyinto elula kakhulu ukuthi ukubunjwa okusetshenziselwa ukukhishwa kwamakheli amatshe ukuvumela ukususwa kalula komkhiqizo oqedile.
Ungenza kanjani ukubunjwa kwe-silicone ngamatshe?
Amafomu anjalo angenziwa ngezandla zawo. Ngakho, ubuchwepheshe bokukhiqiza kwabo yilokhu:
- Thatha ibhokisi elenziwe ngomumo lokugcwalisa isikhunta (matrix) noma uzenze ngokwakho. Kufanele kwenziwe ngezinto eziqinile, ezifana ne-chipboard, fiberglass, amabhodi enkuni, njll. Sicela uqaphele ukuthi akufanele kube khona izikhala phakathi kwezinhlangothi zebhokisi elinjalo, lapho kutholakala khona ukuvuza kwe-silicone.
- Ngaphansi kwe-matrix sibeka i-plastiki engama-sculptural (hhayi ukuzikhandla, kodwa evamile). Lungisa ungqimba lwayo ukuya cishe engxenyeni yebhokisi. I-plasticine kumele ihlanganiswe kahle, ukuze ilale phansi futhi.
- Ukusuka ngenhla nge-plasticin sibeka imodeli eyenziwe ngayo ifomu. Kungaba ngamatshe kunoma yikuphi ukuma noma i-tile ekulungele ngaphansi kwetshe.
- Ukuze ugweme ukuguquguquka kwesimo, kuyadingeka ukwenza izimbobo eziningana zobumba esikhathini esizayo - ukuvala.
- Manje sibala ukuthi kunesidingo esingakanani sokwakha ifomu esidingekayo. Ukuze wenze lokhu, thatha noma iyiphi impahla eningi, uwuthululele esibunjini, bese uyiphululela ekomishini yokulinganisa uphinde ulinganise ivolumu.
- Khona-ke i-matrix kumele iphathwe ngehlukanisi. Kungaba isoya
isisombululo, i-grease, i-wax noma uhlelo lokuhlukanisa okhethekile. Ungasebenzisi noma yimaphi amakhemikhali asekelwe ku-abicah. - Hlanganisa izithako zobuningi bokubunjwa njengoba kuboniswe emiyalweni, bese uthele ama-silicone ku-matrix. Lokhu kufanele kwenziwe ngokucophelela, ngendlela eqondile, eqala ngomjikelezo wokuma ukuvimbela ukwakheka kwamabhulebhu.
- Uma ingxenye engenhla iqina, i-plasticine kufanele isuswe ngokucophelela, indawo kanye nesimodeli kufanele ifakwe nge-separator bese isetshenziswe nge-silicone engxenyeni yezibili ezimbili.
- Ngolunye usuku ifomu lihlukanisiwe, futhi imodeli isuswa kumatrix. Sekulungele ukusebenzisa!
