Iingxowa zokupakisha iifilim ubukhulu becala zenziwe ngeendlela zokutywinwa kobushushu, kodwa zikwasebenzisa iindlela zokudibanisa ukuvelisa.Ngokwemilo yejometri, ngokusisiseko inokwahlulwa ngokweendidi ezintathu eziphambili:iingxowa ezimilise okwemiqamelo, ezinamacala amathathu ezitywiniweyo, ezinamacala amane ezitywiniweyo.
Iingxowa ezinomqamelo
Iibhegi ezimile okomqamelo, ezikwabizwa ngokuba ziibhegi zokutywina ngasemva, iingxowa zinemithungo yomva, ngaphezulu nasezantsi, zizenza zibenemilo yomqamelo, iibhegi ezincinci zokutya ezininzi ezidla ngokusetyenziselwa ukupakisha.Isikhwama esifana nomqamelo emva komthungo ukwenza ipakethe efana ne-fin, kwesi sakhiwo, ifilimu yangaphakathi ihlanganiswe ukuze itywinwe, i-seams iphuma ngasemva kwesikhwama ifakwe.Olunye uhlobo lokuvala ekuvaleni okuthe kratya, apho umgca wangaphakathi kwelinye icala udityaniswe kumgangatho wangaphandle kwelinye icala ukwenza ukuvalwa kweflethi.
Itywina eliqingqiweyo lisetyenziswa ngokubanzi kuba linamandla kwaye linokusetyenziswa nje ukuba umaleko wangaphakathi wezinto zokupakisha uvalwe ubushushu.Ngokomzekelo, iingxowa zefilimu eziqhelekileyo eziqhelekileyo zine-PE yangaphakathi kunye ne-laminated base material layer yangaphandle.Kwaye i-overlap-shaped-shaped-shaped-shaped-shaped-shaped less, kwaye ifuna ukuba iileyile zangaphakathi nangaphandle zesikhwama zizinto zokutywinwa kobushushu, ngoko ke akukho ninzi yokusetyenziswa, kodwa kwizinto eziphathekayo kunokugcina kancinci.
Umzekelo: iingxowa ze-PE ezingaxutywanga zingasetyenziswa kule ndlela yokupakisha.Isitywina esiphezulu kunye nesitywina esisezantsi ngumaleko wangaphakathi wempahla yebhegi edityaniswe kunye.
Iingxowa ezivaliweyo ezinamacala amathathu
Ingxowa yokutywina enamacala amathathu, oko kukuthi, ingxowa inemithungo emacala amabini kunye nomthungo ongaphezulu.Umgca ongezantsi wesikhwama uqulunqwa ngokugoqa ifilimu ngokuthe tye, kwaye zonke iivalelo zenziwa ngokudibanisa izinto zangaphakathi zefilimu.Iibhegi ezinjalo zinokuba nazo okanye zingabi nayo imiphetho esongwayo.
Xa kukho i-edge esongiweyo, banokuma ngokuthe tye kwishelufu.Ukwahluka kwesikhwama sokutywina esinamacala amathathu kukuthatha umda ongezantsi, owenziwe ekuqaleni ngokugoqa, kwaye ufezekise ngokudibanisa, ukuze ube yingxowa yokutywina emacala amane.
Iingxowa ezine ezivaliweyo
Izikhwama zokutywina ezine ezinecala, ngokuqhelekileyo zenziwe ngezinto ezimbini ezingaphezulu, emacaleni kunye nokuvalwa komphetho ophantsi.Ngokwahlukileyo kwiingxowa ezikhankanywe ngaphambili, kunokwenzeka ukwenza isikhwama sokutywinwa esinamacala amane kunye ne-front edge bonding ukusuka kwizinto ezimbini ezahlukeneyo zeplastiki ze-resin, ukuba zinokudibaniswa komnye nomnye.Iingxowa zokutywina ezinamacala amane zinokwenziwa kwiimilo ezahlukahlukeneyo, ezifana nentliziyo okanye i-oval.
