Ezweni eliyinkimbinkimbi lokuklama kwangaphakathi nezinto zokwakha, iphepha lodonga eline-foam lidale indawo ngenxa yokuthungwa kwalo okuyingqayizivele, ukuvikela umsindo, kanye nokuguquguquka kobuhle. Enhliziyweni yokusebenza kwalo okumangalisayo kukhona ingxenye evame ukunganakwa kodwa ebalulekile: iziqinisi zoketshezi. Lezi zithasiselo ezikhethekile zisebenza njengesisekelo sokuqinisekisa ukuqina kwephepha lodonga eline-foam, ukucutshungulwa, kanye nokuhambisana kwemvelo. Ake sihlole imisebenzi ebalulekile enikezaisiqinisi sokushisa se-PVC esiwuketshezikubalulekile ekukhiqizweni nasekusetshenzisweni kwephepha lodonga elinegwebu.
1. Ukuzinza Kokushisa: Ukuvikela Ukuguqulwa Okubangelwa Ukushisa
Ukukhiqizwa kwephepha lodonga elinegwebu kuhilela izinqubo zokushisa okuphezulu, njengokukhipha kanye nokuhlelwa kwekhalenda, okungafinyelela amazinga okushisa afinyelela ku-200°C. Phakathi nale misebenzi, i-polymer matrix yephepha lodonga isengozini yokuwohloka kokushisa, okuholela ezinkingeni ezifana nokuqhekeka kobuso, ukuphambuka kombala, kanye nobuthakathaka besakhiwo. Iziqinisi zoketshezi zisebenza njengabalindi bokushisa, zivimbela ama-free radicals akhiqizwa ukuvezwa ukushisa. Ucwaningo oluvela kwi-Wallcovering Manufacturers Association lubonisa ukuthi ngaphandle kweziqinisi ezifanele, amasampula ephepha lodonga elinegwebu ahlangabezana nokwehla okungu-40% kwamandla okubamba ngemva kwemizuzu eyi-15 kuphela ku-180°C. Ngokuphambene nalokho, iphepha lodonga eline-elungiselelweisiqinisi soketsheziAma-formulations agcina amandla awo angaphezu kuka-85%, okuqinisekisa ukuthi izinto zigcina ukuma nobuqotho bazo ngesikhathi sokufakwa nokusetshenziswa isikhathi eside, ngisho nasezindaweni ezinokushintshashintsha kwezinga lokushisa okuphezulu, njengekhishi noma amakamelo akhanyiswe yilanga.
2. Ukulondolozwa Kwesakhiwo Segwebu: Ukuthuthukisa Ukufana Kwamaseli Nokuzinza
Ukuthungwa okuhlukile kanye nokukhanya kwesithombe sangemuva esine-foam kuncike ku-foam yeselula ehlelwe kahle. Iziqinisi zoketshezi zidlala indima ebalulekile ekulawuleni inqubo yokugqwala, ukuqinisekisa ukwakheka kwezakhiwo zamaseli afanayo, avaliwe. Ngokulawula ukwakheka nokukhula kwama-bubble egesi, lezi zithasiselo zivimbela izinkinga ezifana nokuwa kwamaseli, ukuhlangana, noma ukusatshalaliswa okungalingani. Isibonelo, ocwaningweni lokuqhathanisa iphepha lodonga eline-foam elisekelwe ku-PVC, amasampula anama-liquid stabilizers abonise ukwanda okungu-30% kobuningi bamaseli kanye nokwehla okungu-25% kokwehluka kosayizi wamaseli uma kuqhathaniswa nalawo angenayo. Lokhu kuphumela ekuthungeni okuhlala njalo kobuso, izakhiwo zokuvikela ezithuthukisiwe, kanye namandla emishini athuthukisiwe, okwenza iphepha lodonga limelane kakhulu nemithelela nokuguguleka.
Imboni yamaphephadonga isesicongweni senguquko yezobuchwepheshe, kanye nezinzinzisi zoketshezi ezihamba phambili ekusunguleni izinto ezintsha. Abacwaningi bayahlolaukwakheka kwe-stabilizer okunemisebenzi eminingiezihlanganisa izakhiwo zendabuko zokuzinzisa nezinzuzo ezengeziwe, njengomsebenzi wokulwa namagciwane, amakhono okuzihlanza, noma ukumelana ne-UV okuthuthukisiwe. Lezi zintuthuko azigcini nje ngokuthuthukisa ukusebenza kanye nobude bephepha lodonga elinegwebu kodwa futhi zivula amathuba amasha okusetshenziswa kokuklama kwangaphakathi. Ngaphezu kwalokho, ukuthuthukiswa kweziqinisi ezihlakaniphile ezingasabela ezicini zemvelo, njengokushintsha kwezinga lokushisa noma umswakama, kunesithembiso sokudala izinto zephepha lodonga eziguquguqukayo ezingalungisa izakhiwo zazo ngokuguquguqukayo ukuze zihlangabezane nezidingo zezikhala ezahlukene.
Ekuphetheni, iziqinisi zoketshezi zingaphezu nje kwezithasiselo; ziyizici ezibalulekile zokwenza iphepha lodonga elinogwebu lisebenze kahle kakhulu, lithembeke, futhi lihlale isikhathi eside. Njengoba isidingo sezinto zokwakha zangaphakathi ezisezingeni eliphezulu nezinobungani nemvelo siqhubeka sikhula, indima yeziqinisi zoketshezi izoba yinto ebaluleke kakhulu, iqhube ukusungula izinto ezintsha futhi yakhe ikusasa lemboni yamaphepha lodonga.
