Njengoko amashishini amaninzi asebenzisa isantya esiphezulu
ukupakisha okuzenzekelayo umatshini, kwinkqubo yokupakishwa okuzenzekelayo kwesantya esiphezulu sefilimu yokupakisha eguquguqukayo yeengxowa ezikrazukileyo, ukuqhekeka, ukuchithwa, ukutywinwa kobushushu, iingxaki ezisemgangathweni zokutywinwa ezifana nongcoliseko ngokuthe ngcembe zibe yimfuno yeshishini lokugxila kwiingxaki zenkqubo yokulawula.
Amashishini okupakisha aguquguqukayo kwimveliso yomatshini wokupakisha onesantya esiphezulu usebenzisa i-reel yefilimu, kufuneka athathele ingqalelo oku kulandelayo:
1, umqulu weemfuno zezinto zomaleko wefilimu
ngenxa yesantya esiphezulu umatshini wokupakisha umatshini isakhiwo sezixhobo zahlukile komnye umatshini wokwenza ibhegi, uxinzelelo lwawo kumavili amabini kuphela okanye inqaku elishushu elicinezelayo linyanzelise omnye komnye ukufezekisa ukutywinwa kobushushu, kwaye akukho sixhobo sokupholisa, umaleko wefilimu yoshicilelo unxibelelana ngokuthe ngqo. isixhobo sokutywina ubushushu, ngaphandle kokukhuselwa kwelaphu lokugquma.
Ke ngoko, ushicilelo olukhawulezayo olukhethiweyo ngalunye lwemathiriyeli lubaluleke kakhulu.
Uya kuhambelana neemfuno ezingaphakathi kolu luhlu lungezantsi:
2, ezinye iipropati kufuneka zihambelane ne:
1)
Ibhalansi yobukhulu befilimu
ubukhulu befilimu yeplastiki, ubukhulu obuqhelekileyo kunye nokunyamezela kobunzima, kuhlalutyo lokugqibela bubunzima be-diaphragm.
Kwinkqubo yokuvelisa kufuneka ilawule ukufana kobunzima befilimu, ngaphandle koko iimveliso eziveliswayo, ayisiyomveliso ilungileyo, imveliso elungileyo kufuneka ime nkqo kwaye ithe tyaba ukuya kubunzima bokulingana.
Ngenxa yeendidi ezahlukeneyo zempembelelo yokusetyenziswa kwefilimu ebhityileyo yahlukile, umyinge wobunzima kunye nokunyamezelana kobunzima kwahlukile.
Malunga nesantya esiphezulu esizenzekelayo sokupakisha umahluko wobukhulu befilimu ayikho ngaphezulu kwe-15 um.
2)
Iimpawu ezibonakalayo zefilimu ezincinci
ibhekisa kwinkungu, ukungafihli, ukuhanjiswa kokukhanya kweefilim ezibhityileyo.
ngenxa yoko, umqulu wefilimu ekukhetheni izongezo ze-masterbatch kunye nobuninzi bokongeza uneemfuno ezikhethekileyo kunye nolawulo, kwaye unokufiphala okuhle, kodwa ufuna ukuqwalasela isini esivulekileyo kunye neqondo eligudileyo le-membrane, idosi evulekileyo yokuqengqeleka kwefilimu, ukujija. , akwenzeki phakathi kokunamathela kwefilimu kumgaqo.
Ukuba isixa esikhulu siya kuchaphazela inkungu yefilimu.
Ukukhanya jikelele kufuneka kube ngaphezu kwama-92%.
3)
I-coefficient yefriction
i-coefficient of friction inokohlulwa ibe yi-static friction kunye ne-dynamic system ye-friction.
Iimveliso zomgqomo wokupakisha ngokuzenzekelayo, ukongeza kwimeko yesiqhelo yovavanyo lwe-friction coefficient, kufuneka kwakhona ivavanye ifilimu kunye ne-coefficient ye-friction yepleyiti yensimbi engenasici, ngenxa yokuba umaleko wokutywina ubushushu befilimu yokupakisha ngokuzenzekelayo inxibelelana ngokuthe ngqo nomatshini wokubumba ozenzekelayo. i-friction coefficient kufuneka ibe ngaphantsi kwe-0.
4u.
4)
Yongeza ithamo
ngokubanzi kufuneka ilawulwe ngaphakathi kwe-300 ~ 500 PPM, impembelelo encinci yokuvuleka, njl. Umsebenzi we-membrane, kakhulu uya kutshabalalisa amandla adibeneyo.
Kwaye ukuthintela izongezo kwinkqubo yokusebenzisa inani elikhulu lokufuduka okanye ukungena.
Yongeza idosi kwii-500 ~ 800 iinxalenye kwisigidi ngasinye, kufuneka isetyenziswe ngononophelo, i-dosages eyongezelelweyo enkulu kune-800 PPM, ngokuqhelekileyo ayisebenzisi.
5)
I-membrane edibeneyo ye-synchronous kunye ne-asynchronous contraction
Ufinyezo lwe-asynchronous luqulethwe kutshintsho lwempahla yokugoba kunye ne-warping, ukuncipha kwe-asynchronous kunokuvulwa kwengxowa & nezinye;
Curl ngaphakathi & kuyo yonke;
Okanye & nezinye
Umjikelo wangaphandle & kuyo yonke;
Iintlobo ezimbini zeefom, eli lizwe libonisa ukuba ifilimu edibeneyo ukongeza kwi-synchronous contraction isekhona ngaphakathi kwe-asynchronous contraction (
Uxinzelelo lwe-thermal okanye kwicala elahlukileyo kunye nobukhulu bokuncipha)
.
Ke xa kuthengwa ifilimu, kufuneka ibekwimeko efanayo, kuzo zonke iintlobo zezinto ezihlanganisiweyo ze-thermal (
Kushushu kwaye kufumile)
Uvavanyo lwe-Longitudinal kunye ne-transverse shrinkage, kwaye umahluko wezo zimbini awukwazi ukuhluka kakhulu, malunga ne-0.5% ngcono.
Ezi zilinganisi zineentloko ezininzi zenzelwe ukusebenza njengesikhokelo kubanini bamashishini malunga nokuba bangawachonga njani amathuba anokubakho okutshintsha izinto ezintsha kunye nendlela yokuziqhelanisa neetekhnoloji eziguqukayo zanamhlanje.
