Thumba Losungiramo Zinthu Zosawoneka Bwino Loletsa Nkhungu Sitolo ya Zipatso ku Supermarket Malo Osungiramo Masamba ndi Zipatso Matumba Apulasitiki Opumira

Matumba osungiramo zinthu zatsopano okhala ndi mipata yochepa, matumba osungiramo zinthu zatsopano omwe sachita chifunga, matumba apadera opaka zipatso ndi ndiwo zamasamba m'masitolo akuluakulu, ndi matumba osungiramo zinthu zatsopano a zipatso ndi ndiwo zamasamba omwe sachita chifunga m'masitolo akuluakulu, kodi mwawaona?
Matumba oletsa chifunga ndi matumba apulasitiki okhala ndi zinthu zoletsa chifunga. Matumba apulasitiki ndi tinthu ta pulasitiki tisanayambe kupangidwa. Tinthu toletsa chifunga ndi tinthu ta pulasitiki tosiyanasiyana timasakanizidwa pamodzi, ndipo matumba apulasitiki opangidwawo ndi matumba oletsa chifunga.
Choletsa kuzizira chimapangidwa ndi thovu lokhala ndi mpweya wothira, cristobalite ndi silika ndi ufa wina waung'ono. Pambuyo powonjezera, chimatha kukonza kuzizira, kuyamwa kwa ethylene, kuyamwa madzi, mabakiteriya ndi zina zomwe zili mu filimuyi. , Masamba amatenga gawo loletsa chifunga komanso kusunga.
Popeza mtengo wa mankhwala oletsa chifunga ndi wokwera kwambiri, mtengo wake ndi wowirikiza kawiri kuposa tinthu ta pulasitiki, ndipo umafuna njira inayake, palibe makampani ambiri omwe amadziwa bwino njira imeneyi, kotero mtengo wa matumba oletsa chifunga nawonso ndi wokwera kwambiri.
Masterbatch yoteteza chifunga singagwiritsidwe ntchito kokha posunga ndi kunyamula zipatso ndi ndiwo zamasamba kutentha kwa chipinda, komanso ingagwiritsidwe ntchito posunga ndiwo zamasamba, zipatso, nyama, ndi zina zotero mufiriji (monga firiji m'firiji ndi m'malo ozizira). Imachotsa vuto la zotsatira zosakhutiritsa za masterbatch yoteteza chifunga pamene ili pafupi ndi zero, ndipo siimayambitsa sera pa mipukutu yozizira popanga mafilimu opangidwa ndi opanga.
Ubwino wa masterbatch yatsopano yolimbana ndi chifunga posungira chakudya pogwiritsa ntchito polyethylene blow molding ndi filimu yopangidwa ndi cast ndikuti imagwira ntchito mwachangu kuposa chinthu choletsa chifunga chomwe chili mufilimu yam'mbuyomu ya multilayer kapena single-layer. Imachepetsa nthunzi yamadzi ndikusungunuka kukhala filimu yamadzimadzi, zomwe zimapangitsa kuti pulasitiki iwoneke bwino komanso yowonekera bwino; yotsika mtengo, yotsika mtengo, ndipo imatha kuwonjezera kwambiri kuwonekera bwino kwa filimu komanso kunyezimira kwa pamwamba.
