Analysis na PVC Stretch Fabric Forming Processing
PVC shimfiɗa masana'anta, kayan haɓaka mai ƙarfi da ɗorewa, ana amfani dashi sosai a samfuran waje, tantuna, yadudduka na talla, da kayan kariya na likita. Tsarinsa na ƙirƙira yana tasiri kai tsaye kaddarorin samfurin na zahiri da rayuwar sabis, yana mai da shi mahimmanci don ƙware ainihin kwararar tsari.
Tsarin samar da masana'anta na PVC mai shimfiɗa ya ƙunshi matakai huɗu masu mahimmanci: haɗaɗɗen ɗanyen abu, candering extrusion, mikewa da daidaitawa, da post{0}aiki. Na farko, polyvinyl chloride (PVC) resin yana haɗe shi da abubuwan da ake ƙarawa kamar su robobi, stabilizers, da man shafawa daidai gwargwado kuma ana watsewa daidai gwargwado a cikin babban abin haɗaɗɗiyar sauri{2} don samar da manna tare da takamaiman danko. Zaɓin abubuwan ƙari a wannan matakin kai tsaye yana shafar sassauƙar kayan, juriyar yanayi, da juriyar UV.
Daga nan sai cakudar ta shiga cikin abin da ake fitar da shi, inda ake narkar da shi a matsanancin zafin jiki (kimanin digiri 160{1}}180) sannan a fitar da shi ta hanyar T-die a cikin takarda. Sannan ana yin candered ɗin takardar da rollers don sarrafa kauri da santsi. Dole ne a sarrafa yanayin zafin kalandar daidai don guje wa ruɓewar abu saboda yawan zafi ko damuwa na ciki wanda ya haifar da rashin sanyaya.
Mikewa da fuskantarwa shine ainihin tsari wanda ke ba da masana'anta na PVC mai shimfiɗa tare da babban elasticity. An riga an yi zafi da takardar (yawanci 80-120 digiri) kafin a miƙe shi gaba ɗaya ko bixially a cikin na'ura mai tsayi ko madaidaiciya. Matsakaicin madaidaicin shine yawanci sau 2-5, yana daidaita sarƙoƙin ƙwayoyin cuta a cikin hanyar ƙarfi, yana haɓaka haɓakar kayan haɓakawa da juriya sosai. Wasu samfura masu tsayi suna amfani da fasahar miƙewa jere don ƙara haɓaka ma'aunin inji.
A ƙarshe, masana'anta da aka shimfiɗa suna jurewa yanayin zafi da sanyaya. Saitin zafi ya ƙunshi ɗan gajeren lokaci na babban zafin jiki (kimanin 100{4}}130 digiri) don daidaita tsarin ƙwayoyin cuta da kawar da saura damuwa. Ana yin sanyaya da iska ko ruwa don tabbatar da kwanciyar hankali. Wasu samfuran kuma suna buƙatar jiyya na saman ƙasa, kamar surufi masu jurewa UV ko masu riƙe wuta, don haɓaka aiki.
Tsarin gyare-gyare don masana'anta mai shimfiɗa PVC yana buƙatar kulawa da zafin jiki, saurin gudu, da sigogin tashin hankali. Sabanin kowane mataki na iya haifar da ƙarancin aikin kayan aiki. Ci gaban fasaha, irin su gabatar da sa ido kan layi da sarrafawa ta atomatik, suna haifar da matakai na zamani zuwa mafi inganci da abokantaka na muhalli, suna samar da ingantacciyar mafita ta kayan aiki don aikace-aikacen ƙasa.
