Yintoni PVC bhanyabhanya eliphawulwe ngayo

izinto Packaging ziye zaba enye lweentlobo eziphambili iimveliso ndiyaphela shishino kwinkulungwane XX. Kukho zonke izizathu ukucinga ukuba ukubaluleka kwabo kule nkulungwane kuya kwandisa kuphela. A indawo ekhethekileyo phakathi kwezi zinto kuthatha PVC film (PVC).

Packaging kufuneka enze imisebenzi emininzi. Its njongo ephambili - ukhuselo Product ukusuka ngolunya iimpembelelo yangaphandle, ubumdaka umonakalo ngexesha zothutho kwinkqubo yokuthengisa. Kunye neminye imiba ebalulekileyo enefuthe kwizizathu lomthengi, ezifana lanjengembonakalo enomtsalane kunye nokuzithemba yokuba ngaphambili kwisifundo wakhethwa akukho namnye esetyenzisiweyo okanye wayichukumisa kuye. PVC ifilimu ithelekiseka kunye iipropati best yeplastiki enombala kwaye kungenzeka ngokusebenzisa upakisha zokutya ezininzi.

PVC kunegalelo ukusasazeka elula isizalwane ubuchwepheshe. A izinto Umthombo granular (Polymer) iya kufakwa kwi extruder apho kunyibilika. Emva koko ophephuka ukusuka kwiqamza enkulu, nto leyo esebenza umthombo umaleko rhoqo, bahlabeka ububanzi okunqwenelekayo isilonda bobbins.

PVC ifilimu esetyenziswa kwishishini yokutya kunye norhwebo, yenziwe iintlobo ezimbini ukuzolula kunye shrinkable nobushushu. Ngamnye kubo injongo yayo.

Yolula - PVC ifilim isetyenziselwa ukugquma urhwebo lwayo ngaphandle kokudala weld. Lubonakala yi iipropati ezikhethekileyo ngomatshini, ezifana nokukwazi ukuba olule kunye interlayer adhesion ngenxa ukuyilwa kwe esigangeni electrostatic nezinomtsalane aphakathi. Isetyenziswa ngokubanzi yimibutho zorhwebo ukudala iimeko ucoceko ngexesha ukugcinwa kunye nokuthengiswa kwempahla.

PVC akayeki umboniso luphawulwa ukukwazi ukunciphisa nemilinganiso zejometri phantsi kwempembelelo ubushushu. Ukuze ndipakishe iimpahla kuyo, kufuneka enze imisebenzi emibini esisiseko eyile: kummandla solder nesihlalo. Oveliswa ngokohlobo enesiqingatha-ngaphakathi (ngamanye amazwi, agobe ezinesiqingatha ububanzi) okanye imikhono, eyenze ngo rolls. Uphawu lusebenze weldres mveliso, amaxa amaninzi, emboxo, waza wenza ehleli, ngokokuqhelekileyo air flow shushu.

Kuxhomekeka kuhlobo impahla zipakishwe, ukusuka kuluhlu ezifumanekayo ezivenkileni, umsebenzisi ukhetha ubukhulu oyifunayo. Iimpawu shrinkable ifilimu ngesiqhelo ecacileyo zokumakisha. Umzekelo, ikhowudi eziprintiweyo kwileyibhile PVCT 400 * 750 * 15 kuthetha ukuba umqulu isiqingatha-kwisingxobo ukuba ububanzi-40 cm, kubude 750 m, kwaye ububanzi umaleko yi microns-15.

Kubavelisi PVC ngokuyimfuneko abonisa ubunzima. Ngokwembali, ukuthi ifilimu PVC ithengiswa yi ubunzima.

Kukho olu hlobo izinto zokubopha kunye nokungabikho - on nciphisa film akakwazi uprinte okubhaliweyo okanye imifanekiso, njengoko nayiphi imibhalo ziya igqwethekile xa ukutshintsha kumlinganiselo yemigca. Kodwa ke, umgangatho ogudileyo kulula ukuba babambelele nayiphi ileyibhile okanye, kungenjalo, Somrhaqa ezantsi kwayo. Ngokukhetha le ndlela sobhaliso urhwebo, kufuneka kukhunjulwe ukuba umboniso nciphisa kudala yangaphandle umaleko optically ngaphaya likhusela ngokuchaseneyo imikrwelo, uthuli, ubumdaka, kunye nokunika nayiphi na, nkqu ibhokisi liphelelwe ukhanye ecwebezelayo.

Ukumakishwa PVC ukuzolula film efanayo njengoko ubushushu-shrinkable, umahluko silele yokuba kubhaliwe nenxeba umaleko ube mnye, ngoko ke badla eziwela ubude kabini.
