isicelo

Ifilimu ye-PVC ye-calendering luhlobo lwe-cell evaliweyo ye-foam egqunywe iplastiki eyenziwe nge-polyvinyl chloride resin njengesiseko sezinto, ukongeza i-agent ekhupha ugwebu, i-stabilizer kunye nezinye izinto ezincedisayo, emva kokuxova, ukugoba ibhola, ukubumba kunye nogwebu.Ukongeza kwiipropathi ezithambileyo nezilukhuni zeemveliso zobuchwepheshe, kukho iintlobo ezintathu zomgangatho othambileyo, umgangatho ophukileyo wenkomo kunye nomgangatho.

Ifilimu ye-calendering ye-PVC yenziwa yinkqubo ye-calendering, i-calendering ibubushushu beplastiki ye-PVC ngokusebenzisa isibini okanye izibini ezingaphezulu zomsantsa ojikelezayo ojikelezayo, ukuze izinto eziphantsi kwe-extrusion, ulwandiso, kwaye ube yimveliso ebhityileyo enobunzima obuthile, ububanzi kunye nobukhulu obuthile. inkqubo yomphezulu ogudileyo.Ifilimu ye-Polyvinyl chloride ejikelezayo idlala indima ebalulekileyo kwifilimu yeplastiki.Ukongeza, isetyenziswa ngokubanzi kwi-salting sheet, ukupakishwa kwamashishini, ukugquma kombane, iimveliso zefilimu ezithambileyo, intengiso yebhokisi yokukhanya, ubunjineli obungangeni manzi, ukupakishwa kwezinto eziyimfuneko zemihla ngemihla njalo njalo.

Isizathu sokuba ifilimu ye-Calendering ye-PVC isetyenziswe ngokubanzi kukuba inezi mpawu zilandelayo.

Amandla aphezulu okuqina

Amandla okuqina kwefilimu ye-PVC yekhalenda ukuya kuthi ga kwi-29MPa.Kwixesha elidlulileyo izaqhwithi zesanti kumntla-ntshona weTshayina, ifilimu ye-PE kunye nefilimu ye-EVA zonakaliswa, kodwa ifilimu yekhalenda ye-PVC yayingagungqi.

Ukusebenza kakuhle kwe-thermal insulation

Njengesigqubuthelo sezindlu zokugcina izityalo zezolimo, iglasi ineyona nto isebenzayo yokugquma kwe-thermal, ilandelwa yifilimu ye-PVC ye-calenning (enamandla okufunxa nge-infrared), kunye nefilimu ye-PE.Ukongeza, ebusuku PVC calendered film insulation ukusebenza kunye neglasi ayifani, nto leyo enenzuzo kakhulu ukukhuthaza ukukhula kwezityalo.

Ukucaca kakuhle

Ifilimu ye-PVC ye-calendring ekubunjweni emva kokukhutshwa kwe-mirror roller, ukugqitywa komphezulu kuphezulu kakhulu, i-phenomenon ye-condensation yamanzi incinci, ngoko ke ukuhanjiswa kokukhanya kuphezulu, okuluncedo kakhulu kwi-photosynthesis yezityalo.

Ubukhulu be-homogeneous

Ngenxa yokuba ifilimu ye-PVC ye-calendered ikwimo ye-drum, i-middle roll igqitywe, i-roll ephantsi ine-pre-strain, kwaye i-roll surface iphantsi, ngoko ukuchaneka kobunzima kuphezulu.

Ukusebenza kakuhle kokubambisana

Ngokweemfuno zokusetyenziswa, ifilimu ye-PVC ye-calendering ingaba yi-welding ephezulu-frequency welding, i-hot bonding kunye neendlela zokubambelela, kulula ukuyisebenzisa.

Ukongezelela, ngokweendlela ezahlukeneyo zokusetyenziswa kwefilimu ye-PVC ye-calendering, inokuhlangatyezwa ngokutshintsha ifomyula yokuvelisa kunye neemeko zenkqubo.
