1. Ukugcwalisa kwezithelo.
Kwiinkomo zomgciwano nokumhla wokushona, ngaphandle kokuthi umtemperethi wokuqalayo wesithelo esebenziswayo (isikeli sesibhedlela nokuxhobo lwesihlobo lesikhatsi, ngeke), okanye ukuphakamiswa kwemfene yezandla ezifanayo, kukhonjwa imitha kusasithelo, ngakho ke iindlela zokubuyiselana kwezithelo ezintshangayo kunye nomthwalo uphume ngquku kakhulu.
Ngakho ke, okanye ngokuqala ukuba isithelo esisebenziyo, isikeli kunye nezinye izinto zingazange ziqhelekile, lokungekho ukuba amagcali angavunyelwe (umdlalo we-A ungene ekugcweni), uzoba ungabuyiselana nokubuyiselana kwezithelo.
Iindlela zokulanda: phambi kokuthi uqhubekise izithelo, hlanganisa uphawu lwe-surface kwe-skeleton kunye no-skin, bheka ukusetshenziswa kumhla wokushona kunye nokumhla ongcwangciso engekuhluphekise imitha esasithelo, sebenzisa amathuluzi ngomoya omkhulu kwi-winter, futhi phinda ubuyekeze umthwalo wokuqalayo kunye no-skeleton; ukuya kuqinisekisa, bheka ukuba umdlalo we-B (noma ukususa umdlalo we-A) ukuba usetyenziswa ngquku kwaye uhlinzekele ukubuyiselana.
2. Ukusuka kwefofi.
Ukusuka kwefofi ifinyelela lokugcina ukuba umphathisi wefofi waculeke ngaphandle komphathisi wesikhephe sesiqinisekileyo, okungakwazi ukubuyiselwa nokusebenziswa, kunomoya osebenza ukuya kumva.
Ingxelo yayo yokuba ngemvula, iintsholo zokuthenga ziziphumeleleyo, uhlalelo lweqela luholeka, fofiyana lufuneka leyiye ngaphandle kokuthi isetyenziswa sikhulu.
Isiboniselo sikulisa ukuthatha amaqhawu namoya, noma ukuphuma imveliso eliphephileyo (ispeedi) ukuvumelanisa amaqhawu nokuthi akhulelwe ngendlela efanelekayo nokuthi kuhlalele kakhulu.
3. Amabhembe alingene.
Amabhembe alingene angithetha ukuba ifofi lifunyenwe kulandelayo noma ayifofise.
Lento ingezantsi kwiimaterial ezinamafokasi engavunyelwe, noma intemperethi iyindala ekupheleni.
Isiboniselo sikulisa ukuthatha amaqhawu, ukuphuma imveliso, ukusetha iindlela, ukuphuma indlela ye-catalyst neefokasi, ukuthi akhulelwe ngendlela efanelekayo.
Uma kunezintaba ezaziphumile kwi-sikrhu enye yenqanawe ngomvume ombili, ingabe lokhu kungabangene nge-inxalenye ye-material A ibeqedwe ngaphandle kokuthi i-foaming agent ibhalekile, ndawonye ukuze uqwalise inqanawe yesithoba lesi-A.
4. Umlilo umphofu omtsheni.
Lokhu kulula kumanywa ngokuba imibuzo yamathetho akuziphumelelako kunye nokusebenza ngokugcizelela kwamathetho we-component B.
Isihloko sokuqala nguqoqa ukubonisa isithoba sesililo se-material B ngokupheleleyo ukuvumela ukuba ubucinci be-isocyanate.
5. Umlilo umthengane omncane.
Kusenzelana nesiqinisekiso somphofu wemlilo, lokhu kulula kumanywa ngokuba imigquga yamathetho ye-component B iyiphakamisanga, ndawonye ukuze uvumele amagquga we-component B (noma vumele ukubonisa imigquga ye-component A).
