Amagqabantshintshi ngophuhliso loshishino lwefilim

Ifilimu eyoluliweyo, ekwabizwa ngokuba yipallet packaging. Yeyokuqala e-China ukuvelisa ifilimu eyolulayo ye-PVC ene-PVC njengesiseko semathiriyeli kunye ne-DOA njenge-plasticizer kunye nomsebenzi wokuzincamathela. Ngenxa yemicimbi yokukhuselwa kwendalo, ixabiso eliphezulu (ngokumalunga ne-PE, indawo encinci yokupakisha iyunithi), ukunwebeka okungahambi kakuhle kunye nezinye izizathu, ifilimu ye-PE stretch yapheliswa ngokuthe ngcembe xa imveliso yasekhaya ye-PE stretch film yaqalwa ngo-1994-1995. Ifilimu eyolulayo ye-PE kuqala isebenzisa i-EVA njengezinto zokuzincamathela, kodwa ixabiso layo liphezulu kwaye limnandi. Kamva, i-PIB kunye ne-VLDPE zisetyenziswa njengezinto zokuzincamathela. Izinto ezisisiseko ngoku ubukhulu becala LLDPE, kuquka C4, C6, C8 kunye metallocene PE. (MPE). Ngoku indawo esemantla eTshayina imelwe yifilimu ethi "TOPEVER" eveliswe yiShandong Topever Group, ephumelele ukuthandwa ngabathengi abavela kumazwe amaninzi.

Ifilimu ye-LLDPE yasekuqaleni yayivuthelwa ifilimu, ukusuka kumaleko omnye ukuya kumaleko amabini kunye noluhlu oluthathu; ngoku ifilimu eyolulayo ye-LLDPE iveliswa kakhulu yindlela yokuphosa, kuba imveliso yomgca wokuphosa ineenzuzo zobunzima obufanayo kunye nokucaca okuphezulu. Ingasetyenziswa kwiimfuno zomlinganiselo ophezulu wokolulwa kwangaphambili. Kuba ukuphosa umaleko omnye akunako ukufikelela kwicala elinye lokuncamathela, indawo yesicelo ilinganiselwe. I-single-layer kunye ne-double-layer casting ayibanzi njenge-three-layer casting ngokubhekiselele ekukhethweni kwezinto eziphathekayo, kunye neendleko zokuqulunqa nazo ziphezulu, ngoko ke isakhiwo se-co-extrusion se-three-layer sifanelekile ngakumbi. Ifilimu eyoluliweyo ekumgangatho ophezulu kufuneka ibe neempawu zokungafihlisi okuphezulu, ubude bobude obuphezulu, indawo enesivuno esikhulu, amandla aphezulu anqamlezayo wokukrazula, kunye nokusebenza kakuhle kokugqobhoza.

Ukuhlelwa kweFilimu eyoluliweyo

Okwangoku, iifilimu ezoluliweyo kwiimarike zohlulwe zibe ziindidi ezimbini: iifilimu ezolula izandla kunye neefilim zokolulwa komatshini ngokweendlela ezahlukeneyo zokusetyenziswa. Ubukhulu befilimu eyolulayo yesandla ngokuqhelekileyo yi-15μ-20μ, kwaye ubukhulu befilimu eyolulayo kumatshini yi-20μ-30μ, ngaphandle kweemeko ezizodwa. Ngokwendlela yokupakisha, ukupakishwa kwefilimu eyolulayo kunokwahlulwa kube yipakethi eyoluliweyo ngesandla, ukupakisha okuthambisayo, kunye nokupakishwa kwangaphambi kokolula. Ihlelwe ngokwezinto eziphathekayo, ifilimu eyolulayo inokwahlulwa ibe yi-polyethylene stretch film, i-polyvinyl chloride stretch film, i-ethylene-vinyl acetate stretch film, njl. ibe yeyona nto iphambili kwiifilimu ezolula. Ngokwesakhiwo sefilimu, ifilimu eyolulayo inokwahlulwa ibe yifilimu eyolulayo yoluhlu kunye nefilimu eyolulayo. Ngokuqhelekileyo, icala elinye kuphela elincangathi, ngoko lidla ngokubizwa ngokuba yifilimu encangathi enecala elinye. Ngokuphuculwa kwezixhobo zokuvelisa ifilimu kunye nobuchwepheshe, iingenelo zeefilimu ezoluliweyo ezinamanqwanqwa amaninzi, ezilungele ukuphucula umgangatho wemveliso kunye nokunciphisa iindleko zemveliso, ziye zanda kakhulu. Okwangoku, iifilimu ezoluliweyo ezinezakhiwo ezinoluhlu olulodwa ziye zehla ngokuthe ngcembe. Ngokweendlela ezahlukeneyo zokubumba kunye neendlela zokusetyenzwa, ifilimu eyolulayo inokwahlulwa ibe yifilimu eyoluliweyo kunye nefilimu eyoluliweyo, kwaye ifilimu eyoluliweyo inomsebenzi ongcono. Ukuhlelwa ngokwesicelo, ifilimu eyoluliweyo inokwahlulwa ibe yifilimu eyoluliweyo yokupakishwa kwemveliso yemveliso (efana nefilimu eyoluliweyo yokupakishwa kwezixhobo zasekhaya, oomatshini, iikhemikhali, izinto zokwakha, njl. .

Yolula iFilimu ekrwada Material

Eyona nto iphambili yefilimu eyoluliweyo yi-LLDPE, kwaye ibakala elibandakanyekayo ikakhulu li-7042. Ngenxa yeemfuno ezikhethekileyo zefilimu, i-7042N, 1018HA, 1002YB, 218N kunye ne-3518CB nayo ingasetyenziswa.

Ukusetyenziswa kwefilimu yoLula

Njengenxalenye eyimfuneko yothutho lwempahla, ifilimu eyolula idlala indima yokulungisa iimpahla. Isetyenziswa kakhulu ekwenzeni iphepha, izinto, ishishini imichiza, izinto zeplastiki ekrwada, izinto zokwakha, ukutya, iglasi, njl.; kurhwebo lwangaphandle kumazwe angaphandle, ukwenza iphepha, ihardware, iikhemikhali zeplastiki, izinto zokwakha, Ukutya, amayeza kunye nezinye iinkalo nazo zibandakanyeka. Kunokuthiwa naphi na apho kukho ukuhanjiswa kwendawo yezinto, kukho ubukho befilimu yethu yolula.

Yolula iFilimu yeMveliso yeZixhobo

Ngokubhekiselele koomatshini, okwangoku izixhobo zokuvelisa ifilimu zasekhaya zahlulwe zibe yimigca ephuma kumazwe angaphandle kunye nemigca yemveliso yasekhaya. Imigca yemveliso evela kumazwe angaphandle ubukhulu becala ivela eItali, eUnited States, naseJamani; imigca yemveliso yasekhaya igxile eJiangsu, eZhejiang, eHebei naseGuangdong. Kwaye iChanglongxing Machinery Manufacturing Factory yaziwa kakhulu eTshayina. Iqela leShandong Topever lizise ngoku inani lemigca yemveliso ethunyelwa kumazwe angaphandle ukuze isebenzisane nemigca yemveliso yasekhaya engaphezu kweshumi yokusasazwa kwemveliso. Ngokutsho kweminyaka emininzi yokuqonda imboni, amandla okuvelisa izixhobo ahluke kwiindawo ezahlukeneyo. Isantya sokuvelisa umgca wemveliso yasekhaya yi-80-150 m / min. Kwiminyaka yakutshanje, izixhobo zasekhaya ezikhawulezayo ze-200-300 m / min zikwinqanaba lophando kunye nophuhliso; ngelixa isantya sokuvelisa umgca ongeniswe kumazwe angaphandle siye sanyuswa ukuya kwi-300-400 m / min, 500 m / min Umgca wesantya esiphezulu uye waphuma. Izixhobo zokuvelisa ifilimu ezolula ziyahluka ngokwexabiso ngenxa yobubanzi obahlukeneyo kunye nezantya zemveliso. Okwangoku, umatshini wefilimu we-0.5m wasekhaya owolula intambo yokusetyenziswa kwesandla yi-70,000-80,000 / isiqwenga, kunye nomatshini wefilimu owolula umatshini yi-90,000-100,000 / iqhekeza; I-1-meter thread yi-200,000-250,000 / iqhekeza; Umgca weemitha ezi-2.0 uphakathi kwe-800,000 kunye ne-1.5 yezigidi / isiqwenga.
