Ifilimu ye-polyvinyl chloride yenziwe nge-polyvinyl chloride resin kunye nezinye izilungisi ngokusebenzisa inkqubo ye-calendering okanye inkqubo yokubumba. Ubukhulu ngokubanzi yi-0.08 ~ 0.2mm, kwaye nantoni na enkulu kuno-0.25mm ibizwa ngokuba yi-PVC sheet. Izixhobo zokusebenza ezisebenzayo ezifana neplastiki, izizinzi, kunye nezinto zokuthambisa zongezwa kwi-PVC resin kwaye ziqengqeleke zibe yifilim.
I-PVC Film Classification
Iifilimu zePolyvinyl chloride (iFilimu yePVC) inokwahlulwa ngokwezigaba ezimbini, enye yifilimu yePVC eyenziwe ngeplastiki, kwaye enye yifilimu yePVC engafakwanga plastiki.
Phakathi kwazo, i-akhawunti ye-PVC enzima malunga ne-2/3 yemarike, kunye ne-akhawunti ye-PVC ethambileyo ye-1/3. I-PVC ethambileyo isetyenziswa ngokubanzi kwimigangatho, iisilingi kunye nomphezulu wesikhumba. Nangona kunjalo, ngenxa yokuba i-PVC ethambileyo iqulethe izinto ezithambileyo (oku ikwangumahluko phakathi kwe-PVC ethambileyo kunye ne-PVC enzima), iba yi-brittle kwaye kunzima ukuyigcina, ngoko ke uluhlu lwayo lokusetyenziswa lulinganiselwe. I-PVC enzima ayinayo i-softeners, ngoko ke ine-flexibility efanelekileyo, kulula ukuyibumba, i-brittle, i-non-toxic kwaye ayingcolisi, kwaye inexesha elide lokugcina, ngoko inophuhliso olukhulu kunye nexabiso lesicelo. Undoqo wefilimu ye-PVC yifilimu ye-vacuum-absorbing ifilimu, esetyenziselwa ukupakishwa komphezulu weentlobo ezahlukeneyo zeepaneli. Ke ngoko, ikwabizwa ngokuba yifilimu yokuhlobisa kunye nefilimu yokuncamathelisa. Isetyenziswa kumashishini amaninzi afana nezixhobo zokwakha, ukupakishwa, amayeza, njl njl. Phakathi kwazo, ishishini lezinto zokwakha lithatha indawo enkulu, lilandelwa lishishini lokupakisha, kunye namanye amashishini amancinci amancinci.
⑴ Ukwahlula ngokwezinto ezisetyenziselwa ukwenza ifilimu: ifilimu ye-polyethylene, ifilimu ye-polypropylene, ifilimu ye-polyvinyl chloride kunye nefilimu ye-polyester, njl.
⑵ Ukuhlelwa ngokusetyenziswa kwefilimu: Kukho iifilimu zezolimo (iifilimu zezolimo zinokwahlulwa zibe ziifilimu zemulch kunye neefilimu zegreenhouse ngokosetyenziso lwazo oluthile); iifilimu zokupakisha (iifilimu zokupakisha zinokwahlulwa zibe ziifilimu zokupakisha ukutya kunye neemveliso ezahlukeneyo zamashishini ngokosetyenziso lwazo oluthile). ifilimu yokupakisha, njl.) kunye neefilimu eziphefumulayo kwiindawo ezikhethekileyo kunye neenjongo ezikhethekileyo, iifilimu ezinyibilikayo zamanzi kunye namafilimu aneempawu ze-piezoelectric, njl.
⑶ Ihlelwe ngokwendlela yokwenza ifilimu: kukho iifilimu ezenziwe ngeplastiki nge-extrusion kwaye zibunjwe ngokuvuthela, ezibizwa ngokuba ziifilimu ezivuthelweyo; Iifilimu ezenziwe ngeplastiki nge-extrusion kwaye emva koko zenziwe ngezinto ezityhidiweyo ezivela emlonyeni wokungunda zibizwa ngokuba ziifilimu eziphosiweyo. ; Ifilimu eyenziwe ngezinto eziluhlaza zeplastiki ezigqitywe ngama-roller amaninzi kwi-calender ibizwa ngokuba yifilimu ye-calendered.
Ukusetyenziswa kwefilimu yePVC
Ngokuqhelekileyo, inani elikhulu le-tape lisetyenziswa kwintsimi yombane. Ngokuxhomekeke kwiimpawu zayo, ingasetyenziselwa i-tape yokukhusela, i-tape yemithwalo, i-identification tape, izitikha zentengiso, i-pipeline tape, njl. iifilimu, njl.
Ifilimu ye-PVC ye-greenhouse eqhelekileyo: Akukho izongezo ezichasayo zongezwa ngexesha lenkqubo yokwenza ifilimu. Ubomi benkonzo yinyanga ezi-4 ukuya kwezi-6. Inokuvelisa ixesha elinye lezityalo. Iyapheliswa ngoku.
Ifilimu ye-PVC yokuguga: Izongezo ezichasene nokuguga zongezwa kwizinto eziluhlaza kwaye ziqengqeleke kwifilimu. Inexesha elisebenzayo lokusebenzisa iinyanga ezisi-8 ukuya kwezili-10 kwaye inokuhanjiswa kakuhle kokukhanya, ukugcinwa kobushushu kunye nokumelana nemozulu.
Izinto zokuhombisa zePVC: Ineempawu zokuchasa ukuguga kunye nokuthontsiza, ukuhanjiswa kokukhanya okuhle kunye nokugqunywa kwe-thermal. Ayinakugcina ukuthontsiza kangangeenyanga ezi-4 ukuya kwezi-6 kwaye inobomi benkonzo obukhuselekileyo beenyanga ezili-12 ukuya kwezili-18. Isetyenziswa ngokubanzi kwaye ngoku yeyona isebenzayo. Iindlu zokugcina izityalo ezigcina amandla elanga ziqale zigqunywe ngemathiriyeli.
Ifilimu ye-PVC enganyangekiyo kwimozulu engeyiyo i-drip-proof-proof: Ukongeza kwimozulu exhathisayo kunye ne-drip-proof, umphezulu wefilimu uye wanyangwa ukunciphisa i-plasticizer precipitation kunye nokufunxa kancinci uthuli, okuphucula ukuhanjiswa kokukhanya kwaye kuluncedo ngakumbi. ukulima ebusika nasentwasahlobo kwiindawo zokugcina izityalo zelanga.
I-PVC inokusetyenziswa njengefilimu ye-mulch, kwaye inani elithile le-masterbatch yombala linokongezwa ukuvelisa iifilimu ezinemibala eyahlukeneyo.
Ifoyile ye-PVC: iplastiki, isinyithi, ifilimu ecacileyo, ukupakishwa okungamaphepha, ukupakishwa kweplastiki, ukupakishwa kwamaplanga, ukupakishwa kwesinyithi, njl.
