Ifilimu ye-Ethylene-Vinyl Acetate Copolymer
Iifilimu ze-EVA, ezivela kwi-Elaistity yazo ezibalaseleyo, zihlala ziveliswa kukuphefumla. Iipropathi zeli filimu zihambelana ngokusondeleyo nomxholo weVinyl Acetate (VA). Njengoko umxholo we-VA uyanda, ifilimu iphucuka ngokwendlela ye-elasticity, uxinzelelo lwamandla, ukumelana nobushushu obuphantsi, kunye nokukhumbula ubushushu. Xa umxholo we-VA ufikelela kwi-15% ~ 20%, ukusebenza kwayo kukuthelekiswa noko kwifilimu ye-PVC. Kwelinye icala, xa umxholo we-VA uphantsi, ukusebenza kwefilimu kufutshane nefilimu ye-LDP. Ngokubanzi, umxholo we-VA kwiFlifithi ye-EVA ilawulwa kuluhlu lwe-10% ~% 20%.
Iifilimu ze-EVA zaziwa ngokungafihlisiyo, ukuthamba, kunye nokuzincama. Eyona ngcinezelo yayo eyonakeleyo yokuqhekeka kwaye i-elasticity ephezulu yenza i-elonghation iphezulu nge-59% ~ ~ 80%, iyenza ifilimu efanelekileyo ye-spiral. Kwicandelo lokupakisha, lisetyenziswa ngokubanzi kwingqokelela kunye nokusonga iibhokisi kunye neempahla ezibiweyo, kunye nokusongelwa kweepallets. Kwangelo xesha, ifilimu yase-Eva ikwafanelekile ekuvelisweni kweengxowa zephakheji zezinto ezinzima ezinje ngezichumisi kunye nezixhobo zohlaza zekhemikhali. Ukongeza, inobushushu obuqaqambileyo obushushu kwaye bhetyelwa kokutywina, kwaye ihlala isetyenziswa njengendawo yokuthengisa iifilimu zefilimu.
Ifilimu ye-Polyvinyl ifilimu
Iindlela zemveliso ze-PVA FILMMs zibandakanya isisombululo sokuphosa isisombululo kunye nokupheliswa kwebhulukhwe. Ngenxa yobushushu obuphezulu be-PGA kunye nokusondela kwayo kwiqondo lokushisa, ukunyibilika ngokuthe ngqo kunzima, ke iplastiki yamanzi ihlala isetyenziselwa ukunciphisa ubushushu bendlela yokulungisa. Ngale ndlela, ifilimu kufuneka yomiswe kwaye ikhutshiwe emva kokubumba ukufumana ifilimu ye-PVA. Kwicandelo lokupakisha, ishishini likhetha ukusebenzisa indlela yokuphosa ukuvelisa iifilimu zePDA.
Iifilimu zePDA zinokwahlulwa zibe ziifilimu ezichaphazela amanzi kunye neefilimu ezinyibilikayo zamanzi. Iifilimu ezinganyangekiyo zamanzi zenziwa nge-PVA enenqanaba le-polymerizazazation elingaphezulu kwe-1000 kwaye lizwe ngokupheleleyo, ngelixa iifilimu ezinyibilikayo zenziwe nge-punsiment ye-puranding ephantsi. Kwizicelo zokupakisha, sisebenzisa ikakhulu iifilimu ze-PVA ezinganyangekiyo.
Ifilimu ye-PVA, emele i-filsarent ebalaseleyo yayo kunye neglosi, ayisiyonto ingapheliyo ekuqokeleleni umbane wombane kunye nokuthathwa kothuli, kodwa ikwanentsebenzo elungileyo yokushicilela. Kwimeko eyomileyo, ibonakalisa ubungqwirha obungaphezulu kunye nokugcina ivumba elimnandi, kunye nokuchasana kweoyile yeoyile. Ukongeza, iifilimu ze-PPA zinamandla amahle, ukuqina, nokunyangwa koxinzelelo, kwaye kunokuba nobushushu. Nangona kunjalo, ngenxa yokufuma kwawo okufumanisayo kunye nokuthathwa kwamanzi okuqinileyo, ukuzinza okuphezulu kufuneka kuphuculwe. Ukulungiselela ukusombulula le ngxaki, i-Polyvinylidene Chloridene Doride, okt, ukukhangela, ihlala isetyenziselwa ukukhulisa ukuqina komoya, ivumba elimnandi kunye nokunganyangeki komswakama. Le filsi ikhutheleyo i-PVA ilungele ukupakishwa kokutya.
Ifilimu ye-PVA ihlala isetyenziswa njengomqobo kwifilimu yefilimu, kwaye isetyenziswa ngokubanzi ekupakisheni ukutya okukhawulezayo, iimveliso zenyama, iimveliso zekhrimu kunye nokunye ukutya. Kwangelo xesha, ifilimu yalo enye isetyenziswa ngokubanzi ekupakisheni amanqwaba kunye nempahla yokunxiba. Ukongeza, iifilimu ze-PVA ezinyibilikayo zamanzi ze-PVA zikwasebenza kakuhle kwimitha kunye nokupakisha iimveliso zekhemikhali ezifana nabasechevini, iingubo, i-daic, i-dach, i-daicides, kunye neengxowa zokuhlamba iimpahla zabaguli.
Nje,Iifilimu zokupakisha zeplastikizibalulekile kwicandelo lokupakisha, kwaye iipropathi zabo ezizodwa zibenza bakwazi ukufikelela kwiimfuno ezahlukeneyo zokupakisha kunye nokufuna.
