1. Hanyar hatimin marufi

Hanyoyin hatimin kunshin sun haɗa da hatimi mai zafi, hatimi mai sanyi, likafa mai laushi, da dai sauransu. Hataccen zafin jiki yana nufin amfani da ɓangaren ɗakunan thermoplastic na ciki a cikin tsarin finafinai da yawa, wanda ke tausasa hatimi lokacin dumama, kuma yana karfafa lokacin da tushen zafi yake cire Ana amfani da filastik hatimi mai zafi, kayan shafe-shafe da narkewar zafi. Hannun sanyi yana nufin cewa ana iya rufe shi ta latsawa ba tare da dumama ba. Mafi sanadin murfin rufewar sanyi shine murfin gefen da aka yi amfani da shi a gefen jakar marufi. Ba safai ake amfani da hatim ɗin m cikin marufi na kayan abubuwa da yawa ba, ana amfani da shi ne kawai don kayan marufi waɗanda ke ƙunshe da takarda.

2. Kayan hatimi mai zafi

(1)Polyethylene (PE) wani nau'ine ne mai launin ruwan madara, mai haske kuma mai yarfafa sosai. Ba shi da ɗanɗano, ba mai daɗi ba kuma ya fi wuta zafi. Sarkar macromolecular ta PE tana da sassauci mai kyau kuma yana da sauƙin murɗawa. Abu ne mai tauri a zafin jiki na ɗaki. A matsayin kayan marufi, babban rashin amfanin PE shine rashin matattarar iska, babban damar iskar gas da tururin kwayoyin, rashin karfi da juriya mai zafi; yana da sauƙin kaskantar da shi ta hanyar haske, zafi da kuma sanda, don haka antioxidant da haske da kwanciyar zafin jiki galibi ana sanya su cikin kayayyakin PE don hana tsufa; PE yana da mummunan matsalar danniya, kuma baya jure lalata lalatawar h2s04, HNO3 da mai sarrafa shi, kuma wasu aliphatic hydrocarbons ko hydrocarbons na chlorinated zasu lalata shi. aikin bugawa na PE ba shi da kyau, kuma farfajiyar ba ta iyakacin duniya ba ce, don haka dole ne a gudanar da maganin corona kafin bugawa da bushewa don haɓaka dangantaka da bushewar haɗin tawada.

PE da ake amfani da shi don kwalliyar hatimi mai zafi ya haɗa da:
Ye polyethylene mai ƙarancin nauyi (LDPE), wanda aka fi sani da matsin lamba mai ƙarfi;
Ye polyethylene mai girma (HI) PE, wanda aka fi sani da suna polyethylene mara nauyi;
Ye matsakaicin matsakaici polyethylene (nu) PE :); arirgar ƙananan ƙananan polyethylene (LLDPE);

(2)Kadarorin Fim din polypropylene (CPP) da aka yi amfani da su don hatimi na zafi sun ɗan bambanta da na polypropylene na daidaitaccen bixi saboda yanayin aikinsa daban. Ana nuna fa'idodi da rashin amfanin CPP a cikin abubuwan da suka dace na "polypropylene".

(3) PVC (gajarta a matsayin PVC) mara launi ne, mai haske da kuma taushi mai ƙarfi tare da iyawar kwayar halitta mai ƙarfi da ƙarfi mai tasirin kwayar halitta, saboda haka yana da taurin kirki da kwalliyar filastik mai tsauri.

PVC ta fi rahusa kuma ta fi dacewa. Ana iya yin shi a cikin kwantunan kwalliya masu tsauri, kumfa masu haske da finafinan marufi masu sassauƙa da kayan matashin kumfa na kumfa. Saboda gubarsa da lalacewarta, yawan amfani da shi yana raguwa kuma a hankali ana maye gurbinsa da wasu kayan.

(4) EVA (ethylene vinyl acetate copolymer) poly (ethylene vinyl acetate) (EVA) poly (ethylene vinyl acetate) (EVA) poly Eva) poly (ethylene vinyl acetate) (EVA) poly (ethylene vinyl acetate) (eva-eva) poly (ethylene vinyl acetate) (EVA) poly (ethylene vinyl acetate) (EVA. EVA translucent ne ko kuma ɗan madara fari mai ƙarfi tsayayye ta hanyar hada kai na ethylene da vinylacetic acid vinegar .Kaddarorinta suna canzawa tare da abubuwan monomers guda biyu.Saboda haka, yayin zabar samfurin EVA, yakamata a tabbatar dashi gwargwadon amfani, kuma za'a iya amfani dashi azaman filastik, mai narkewa mai zafi .
Ana amfani da Eva ko'ina azaman layin ciki na haɗin fim saboda ƙwarewarta da ƙarancin ƙarfin ƙarfin zafi. Ana amfani da shi a cikin mannewa, sutura, sutura, murfin kebul da mai ɗaukar launi tare da mannewa mai kyau (mai kyau ko takamaiman iya aiki tare da kayan polar da yawa da kuma wadanda ba na polar ba).

(5)PVDC (polyvinylidene chloride) PVDC gabaɗaya yana nufin copolymer na vinylidene chloride. A polymer samu ta polymerization yana da babban crystallinity, high taushi aya (185-200′c) da kuma kusa da bazuwar zazzabi (210-2250). Yana da rashin daidaituwa tare da takamaiman janar, don haka yana da wahala a canza shi.
PVDC abu ne mai ƙarfi kuma mai haske tare da babban lu'ulu'u da launin kore. Yana da ƙarancin saurin watsa ruwa zuwa haɗiye gas, gas da ƙanshi, kuma yana da kyakkyawan juriya na danshi, ƙarancin iska da riƙe kamshi. Yana da kyakkyawan kayan shinge mai iyaka. Yana da tsayayya ga acid, alkali da abubuwa daban-daban, mai juriya, mai ƙyama da kuma kashe kansa.
