Filimu yomatira yosungunuka ya H&H: Ndi mtundu wanji wa filimu yomatira yosungunuka yosungunuka yomwe imagwiritsidwa ntchito pomangirira nsapato pamwamba?

Pali mitundu yambiri ya guluu wophatikizika pamsika wa nsapato, ndipo mitundu ndi zipangizo zake ndizosiyana. Kulumikiza nsapato zachikhalidwe nthawi zambiri kumagwiritsa ntchito guluu wamadzi, womwe ndi wovuta kuugwiritsa ntchito, mtengo wokwera wa nsapato, mpweya woipa wolowera, komanso mawonekedwe ake osalimba. Kuphatikiza apo, nsapato zimatha kuumba zikayenda mtunda wautali, makamaka zikatumizidwa ndi nyanja, zomwe zimapangitsa kuti opanga azitaya ndalama zambiri. Chifukwa chake, mafilimu omatira otentha nthawi zambiri amagwiritsidwa ntchito pamsika wa nsapato kuti aziphatikiza, zomwe zimatha kuthetsa vutoli bwino.

Pakadali pano, pali mitundu yambiri ya mafilimu omatira otentha pamsika wa nsapato, monga PES hot melt adhesive omentum, TPU hot melt adhesive omentum, EVA hot melt adhesive omentum, PA hot melt adhesive omentum, PA hot melt adhesive film, ndi TPU hot melt adhesive film. Melt adhesive film, EVA hot melt adhesive film, etc. zingagwiritsidwe ntchito popanga nsapato. Zina ndizoyenera kupanga nsapato pamwamba, zina ndizoyenera kupanga insole compounding, ndipo zina ndizoyenera kupanga nsapato pamwamba. Lero, nkhaniyi ikunena makamaka za nsapato pamwamba. Filimu yomatira yotentha yothira, mwachitsanzo nsapato zachikopa ndi nsapato zamasewera:

Chophatikiza chapamwamba cha nsapato zachikopa ndi nsapato zamasewera chimachokera makamaka ku nembanemba ya TPU yothira madzi. Nembanemba ya hot-melt iyi imakhala ndi mphamvu yayikulu yolumikizira komanso yokana kusamba. Kugwiritsa ntchito nembanemba yamtunduwu kumalumikiza pamwamba kumakhala ndi mpweya wabwino komanso kukana. Fungo, pamwamba pake sipamasuka, kumamatira mwamphamvu kwa filimuyo, ndipo palibe chifukwa chogwiritsa ntchito singano ndi ulusi kuti ilimbikitse, malo omatirawo ndi ofewa, omasuka kuvala, ndipo pamwamba ponseponse ndi okongola kwambiri. Nthawi zambiri, opanga akasankha chophatikiza cha hot-melt omentum, amasamala za vuto la kulemera kwa omentum. Kulemera kumakhudza mwachindunji mulingo wa mgwirizano wa pamwamba. Mphamvu yolumikizira ikakwera, kulemera kwa omentum kumakhala kolemera. Ngati pali zosowa zina zapadera, monga kuletsa madzi, ndiye kuti mutha kusankha filimu ya TPU yothira madzi. Filimu ya TPU yothira madzi imakhala ndi kutentha kochepa kophatikizana, kusinthasintha kwabwino, komanso kosalowa madzi. Ndi yoyenera kwambiri nsapato zothira madzi.
