Qingdao Sainuo gulu linakhazikitsidwa mu 2005, ndi kupanga, kafukufuku wa sayansi, ntchito, malonda monga mmodzi wa mabuku mabuku apamwamba chatekinoloje mabizinesi. 30,000 matani kupanga sikelo, 60,000 matani kupanga ndi malonda mphamvu.
Kampani yathu ili ndi antchito opitilira 100, mafakitale 4, zopangidwa ndi PE, sera ya OPE, sera yosweka kwambiri, sera yomezanitsa, sera yoyengedwa ya FT, sera ya oligomer, Stearic acid, EBS , PETS, Zinc stearate, Magnesium stearate, Calcium. stearate, oleic acid amide, erucic acid amide, coupling wothandizila ndi zina zonse za dongosolo kondomu decentralized njira yoyimitsa imodzi. Masiku ano, Qingdao Sainuo adzakutengerani kuti mumvetse chidziwitso choyenera cha sera ya polyethylene.

1. Kugwiritsa ntchito sera
(1) High kachulukidwe mtundu masterbatch ndi filler masterbatch: amagwiritsidwa ntchito ngati dispersant mu utoto masterbatch processing, chimagwiritsidwa ntchito polyolefin mtundu masterbatch. Zimagwirizana bwino ndi Pe, PVC, PP ndi ma resins ena, ndipo zimakhala ndi zodzoladzola zakunja ndi zokometsera zamkati;
(2) mipope, gulu stabilizers ndi mbiri: iwo ntchito ngati dispersants, lubricant ndi kuwala mu ndondomeko ya PVC, mapaipi, gulu stabilizers, PVC mbiri, zovekera chitoliro, PP ndi PE akamaumba ndi processing kumapangitsanso plasticization digiri, kusintha kulimba ndi kusalala pamwamba pa zinthu zapulasitiki, ndipo amagwiritsidwa ntchito kwambiri popanga ma PVC okhazikika;
(3) Inki: monga chonyamulira cha pigment, imatha kusintha kukana kwa utoto ndi inki, kupititsa patsogolo kubalalitsidwa kwa pigment ndi filler, komanso kukhala ndi anti sedimentation effect. Itha kugwiritsidwa ntchito ngati chothandizira chosalala cha utoto ndi inki kuti zinthuzo zikhale zowala bwino komanso zowoneka ngati zitatu;
(4) Sera: amagwiritsidwa ntchito kwambiri mu sera pansi, sera yamagalimoto, sera yopukutira, makandulo ndi zinthu zina za sera kuti apititse patsogolo kufewetsa kwa zinthu za sera ndikuwonjezera mphamvu zawo ndi gloss pamwamba.
(5) Chingwe zakuthupi: ntchito ngati lubricant wa zinthu chingwe kutchinjiriza, akhoza kumapangitsanso kufalikira kwa filler, kusintha extrusion akamaumba mlingo, kuonjezera nkhungu otaya, ndi atsogolere demoulding;
(6) Zopangira zotentha zotentha: zimagwiritsidwa ntchito pamitundu yonse ya zomatira zotentha zosungunuka, zokutira za ufa wa thermosetting, utoto wapamsewu, etc. monga dispersant, zimakhala ndi anti sedimentation effect ndipo zimapangitsa kuti mankhwalawa azikhala ndi gloss wabwino ndi kumverera kwa mbali zitatu;
(7) Mphira: monga processing thandizo la mphira, akhoza kumapangitsanso kufalikira kwa filler, kusintha mlingo extrusion akamaumba, kuonjezera nkhungu otaya, atsogolere demoulding, ndi kusintha kuwala pamwamba ndi kusalala kwa mankhwala pambuyo demoulding;
(8) Zodzoladzola: kupanga mankhwala kukhala ndi luster ndi kumverera kwa mbali zitatu;
(9) jekeseni akamaumba: kuonjezera gloss pamwamba mankhwala.
(10) Ufa ❖ kuyanika: ntchito ❖ kuyanika ufa, akhoza kupanga mapangidwe ndi kutha, komanso akhoza kukana zikande, abrasion, kupukuta, etc; Kubalalika kwa pigment kumatha kuwongolera.

2. Njira yopangira sera ya polyethylene
Pakali pano, pali njira zitatu zazikulu zopangira sera ya polyethylene: imodzi ndi polyethylene sera yopangidwa ndi oligomerization ya ethylene monomers, monga oligomerization yaulere; Wina ndi sera ya polyethylene yokonzedwa ndi kuwonongeka kwa polima wapamwamba; Chachitatu ndi mankhwala mu ndondomeko ya polyethylene kaphatikizidwe, monga polyethylene sera anapezedwa ndi kulekanitsa ndi mankhwala mu mkulu-anzanu polyethylene synthesis.
(1) Ethylene polymerization
Pali njira zitatu zazikulu zopangira sera ya polyethylene ndi polymerization ya ethylene. Imodzi ndi polymerization yokhala ndi chothandizira chaulere pansi pa kutentha kwakukulu ndi kukakamizidwa; Chachiwiri, polymerization ndi Ziegler chothandizira pansi pa mavuto otsika; Chachitatu, metallocene chothandizira polymerization.
(2) Polyethylene akulimbana njira
The maselo kulemera kugawa polyethylene sera opangidwa ndi polymerization njira ndi yopapatiza, ndi wachibale maselo kulemera akhoza lizilamulira pamanja, koma ayenera kuchitidwa mu chipangizo chachikulu, ndi ndalama lalikulu likulu. Opanga zapakhomo nthawi zambiri amagwiritsa ntchito matenthedwe ang'onoang'ono a polyethylene kuti apange. Zopangira zomwe zimagwiritsidwa ntchito mwanjira iyi zitha kukhala utomoni wa polyethylene kapena pulasitiki wotayirira wa polyethylene. Zakale zimatha kupanga zinthu zapamwamba, pamene zotsirizirazo zimatha kupanga zinthu zotsika. High maselo kulemera polyethylene akhoza thermally losweka mu otsika maselo kulemera polyethylene sera pansi pa chikhalidwe kudzipatula. Zomwe zimakhudzidwa ndi kapangidwe kake (monga crystallinity, kachulukidwe, kuuma ndi kusungunuka) kwa sera ya polyethylene yokonzedwa motere imakhudzidwa ndi zopangira zowonongeka. Kung'amba njira processing amagawidwa akulimbana ketulo njira ndi extrusion njira. Njira yopangira ketulo ndi njira yopangira batch, yomwe ili yoyenera kwa opanga omwe ali ndi mphamvu zochepa komanso zochepa; Extrusion njira ndi mosalekeza kupanga, oyenera mabizinezi ndi mphamvu yaikulu kupanga ndi mphamvu mkulu kupanga.
(3) Kuyeretsedwa kwa polyethylene ndi mankhwala
Polyethylene sera mankhwala akhoza anachira osakaniza otsika maselo kulemera zigawo zikuluzikulu ndi zosungunulira akamagwira ndi-mankhwala kupanga polyethylene ndi ethylene polymerization. Pambuyo pa zosungunulira ndi zoyambitsa zimachotsedwa kuzinthu zopangidwa ndi polyethylene unit, kugawa kwa molekyulu ya mankhwala kumakhalabe kwakukulu, komwe kumachepetsa ntchito yake ndipo kumafuna kuyeretsedwa kwina ndi kulekanitsa zosungunulira. Izi ndi mankhwala polyethylene sera mankhwala kawirikawiri amakhala mamolekyu ndi wachibale maselo kulemera pafupifupi 1000, choncho ndi wotsika kuposa polyethylene sera mankhwala opangidwa ndi ethylene polymerization mwa mawu a mphamvu makina, kukana kutentha ndi zina thupi katundu.

(4) Kusintha kwa polyethylene sera
Polyethylene sera ndi molekyulu yopanda polar. Ngati magulu a polar atha kuyikidwa mu molekyulu, gawo logwiritsira ntchito lidzakulitsidwa kwambiri. Izi functionalized polyethylene sera akhoza kupangidwa ndi copolymerization wa ethylene ndi mpweya munali monomers, ndi magulu carboxyl akhoza anadzetsa polyethylene sera ndi mankhwala njira monga makutidwe ndi okosijeni ndi Ankalumikiza, ndiyeno zina kusinthidwa ndi zimachitikira mankhwala monga esterification, amidation ndi saponification. Izi functionalized polyethylene sera akhoza kukwaniritsa zofunika zosiyanasiyana ntchito.
Malingaliro a kampani Qingdao Sainuo Chemical Co.,Ltd. Ndife opanga sera PE, PP sera, OPE sera, Eva sera, PEMA, EBS, Zinc / Calcium Stearate…. Zogulitsa zathu zadutsa REACH, ROHS, PAHS, FDA kuyesa.
Sainuo chidaliro sera, kulandira atafunsira anu!
