Shwabanisa ngaphakathi: iintlobo, iimpawu, izabelo. Shwabanisa ifilimu

Polyethylene yenye yezinto ezininzi ethandwayo zisetyenziswa ukuphakheja. Oku esetyenziswa kwishishini, mveliso, urhwebo noshishino, Kakade, akakwazi ukwenza ngaphandle kunye Inkosikazi elula. Kwimeko nganye, iphetshana elifanelekileyo ze iimpawu kulo mbandela. Oku kunokuba ipasile, kwaye web bhanya kunye tube zaseprayimari. Umzekelo, ngokwembono lwamaxabiso zokusebenza ukuyishwabanisa kwisingxobo seplastiki kuyinto obesazeka, kwaye zingasetyenziswa njenge njengesiseko iimveliso zokugcina, kwaye arhente olukhuselayo.

Injongo kunye nesiqulatho ifilimu nciphisa

Umsebenzi iphambili yale nto kukuqinisekisa yengxinano ngayo imveliso. Le nto ithintela iziphumo ezibi ngeemeko zokusingqongileyo, ngokukuvumela ukugcina iipropati imveliso ithagethi yentsusa. Sinokuthi ezi iingxaki zisonjululwe uluhlu enkulu impahla izinto, phakathi kwabo kukho uluhlu olubanzi polyethylene oluqhelekileyo. Noko ke, ukukwazi nciphisa emkhonweni kufanelekile snugly eyabelwe kwindawo yokugcina, nto leyo evumela ugcino isithuba ngokusemthethweni packagings zothutho. Apho baya bezisebenzisa le sisombululo? Okokuqala, oko nkampani benza nokwenziwa kunye nokuthengiswa kwemveliso zokutya. ngci kakuhle nokupakisha oxineneyo iimpahla ezifunekayo Zinjengeqhezu iikhemikhali zekhaya, iimveliso zokushicilela, izinto zokubhala nokubhalela ezinye iintlobo zezixhobo zokwakha.

uhlobo

Zonke izinto Shwabanisa ifilimu zahlulwe iiklasi ezintathu uhlobo impahla eluhlaza ezisetyenzisiweyo. Ngoko, ke isisiphumo Polyvinyl chloride (PVC), polyethylene (LDPE) kunye polyolefin (pof) le web. Ngoko nangoko ndiya kuthi ukuba Shwabanisa kumkhono PVC yeyona ethandwa kakhulu ngenxa yokuba Ikwagcina inqanaba ngokwaneleyo yengxinano ngenxa yokugcina ukutya ezininzi, kodwa kwangaxeshanye akuyiphazamisi kunye neenkqubo kunaniselwano gas. Enyanisweni, lo msebenzi, yaye umahluko ophambili phakathi PVC kunye polyolefin. Materials evela pof kwakhona ukwanelisa iimfuno abenzi imveliso, ethe emoyeni, kodwa musa ukuvumela naziphi iigesi kunye umthondo.

Eyahluke kakhulu elide kuba ezinye iimpawu kunye nezinto zeplastiki ezindala. Kwawo zisetyenziswa kumaqela ukugcina iimveliso - umzekelo, iipakethe ezininzi okanye ibhotile umgodlo sheets amaphepha. Loo umboniso nciphisa esibonakala ngamandla ngomatshini, amandla iinyembezi elide.

iimpawu

Imilinganiso ungomnye Indlela zokukhetha le mveliso, ukuba umgangatho abanye kubo ezifanelekileyo. Ngoko ke, lo umboniso akhutshwa poliolefinola kuluhlu ububanzi cm-25 ukuya 90, yaye inowuthi idla yi-5 cm. Ngokubhekiselele balo babulingana nesandla, oko kulo mzekelo kuhluka kuluhlu 12-25 microns. Kubude: imbokodo besukelana 1250 m. Kodwa kwikhaya eqhelekileyo ngokubhijela ayikho ngaphantsi kwe-650 m. Polyvinylchloride nciphisa ekupakisheni sleeve yi uluhlu ngaphantsi engafaniyo. Umzekelo, ububanzi web akufane mkhulu kwe-60 cm, ubude -. 750 m Kodwa PVC ifilimu kwahlukile balo babulingana nesandla, lwathi phezu microns-30. izinto zeplastiki malunga noluhlu ubungakanani efanayo. Ngokobunzima yexabiso avareji ngokubanzi lo uluhlu 5-10 kg, kwimeko kwimiqulu mveliso.

iipropati yokusebenza

Nangona kukho ezinye umehluko ngeempawu kwi izinto ezahlukeneyo ubushushu-shrinkable, umgangatho osisiseko iyafana. Ezi ziquka ukusebenza ngokupheleleyo ukumelana ngomatshini, ukhuseleko yococeko zisempilweni, akukho ukuzolula, kwakunye inertness ukuze imichiza. Kubalulekile ukuphawula, nangokusulela nokukhanya, nto leyo iba Shwabanisa ngaphakathi transparent, esilungiselelwe kwiipakethe zemveliso yokutya. Kodwa bevumelana engundoqo umgangatho nciphisa izinto yabantu abangakwaziyo ngokubanzi, kuba uyakwazi ukuthatha ngokupheleleyo uhlobo kweemveliso iinkonzo. Shrinkage kwi-avareji 40-50% phantsi imeko kakuhle ekhethiweyo parameters unyango ubushushu.

ukwenza izixhobo shrinkage

Ukuze enze umsebenzi unyango ubushushu wathi, phantsi apho kukho ukwehla ngelaphu, besebenzisa izixhobo ezikhethekileyo. Oku kungaba izixhobo oluzenzekelayo okanye semi-oluzenzekelayo yenzelwe ukusebenza kunye iimveliso nobukhulu ethile. Kwakhona, iiyunithi yahlulwe yaba imodeli kwetonela kunye negumbi uhlobo. Le ndlela ngokwahlukana limisela ukukwazi ukusebenza ngeendlela ezahlukeneyo ngokwemiqathango loqukuqelo inkonzo - okanye inxenye serial. Phakathi nokusebenza kwalo msebenzi kwi Shwabanisa intlama kulo nomthamo umoya oshushu. Isiphumo yindibanisela eli laphu ukusebenza, kwaye kuthatha ngokupheleleyo emilise into ukuze nokupakisha. Ukongeza, umatshini nganye iinketho ezongezelelweyo umqhubi emsebenzini lwesiqhelo. Ezi ziquka, umzekelo, ibhekisela umsebenzi ukunciphisa rolls.

Yimalini kwisingxobo nciphisa?

rates ezithile Finyeza-uzimisele ubungakanani eqhelekileyo, zobugcisa parameters kunye nobukho iipropati ezithile ifilimu. Oku akusoloko abalimi ukuvelisa iimveliso iibhetshi ngendlela ethile. Umzekelo, ukuphunyezwa kwenziwa webs ngokobunzima, umthengi oyifunayo. Standard akayeki umboniso ezifumanekayo ezivenkileni umlinganiselo 150-200 engange. / Kg. adlula esibanzi ashinyeneyo zibiza umlinganiselo lamawaka 3-4. 25-30 kg. Kodwa ezi zixa zinxulumene amaqela, eziyilelwe kwiimfuno zoshishino.

isiphelo

iteknoloji ukuncipha landa kakhulu ngobuchule nezinto zokubopha. It ikuvumela ukuba ukunciphisa isithuba ukuba kuhlala consignments ezinkulu, kwaye ngexesha elinye nokugcina inqanaba eyimfuneko iimpawu zokhuselo. Oku inika uyamnika ngokwemigaqo ngezilingo sliding. Modern Shwabanisa sleeve yenziwa kunye indices ezahlukeneyo ububanzi, ubude kunye ubukhulu. Ukuba ukuthathela ingqalelo into yokuba ukusamkela umboniso webs uluhlu olubanzi kwiipropati yokusebenza, unako ukuthetha emhlabeni wonke umbandela. Nangona kunjalo, kukho ezinye imida kwi ukusetyenziswa Shwabanisa film. Ngokomzekelo, izinto ezinjalo ayikwazi ingasetyenziswa ukugcina iimveliso ezibukhali kwaye ibulale abangenawo ukuqulatha. Kukho imida ethile ngokwemigaqo amathuba yokusebenzisa Polyvinyl chloride efanayo kwiqondo lobushushu ezahlukeneyo. Kodwa ngaba balimi umda sifuna ukuba, enika umboniso iimpawu ezongezelelekileyo.
