polyethylene sera imatanthawuza kutsika kwa polyethylene ya molekyulu yokhala ndi mamolekyu olemera osakwana 10000, ndipo kuchuluka kwa kulemera kwa maselo nthawi zambiri kumakhala 1000-8000. Sera ya polyethylene imagwiritsidwa ntchito kwambiri mu inki, zokutira, kukonza mphira, mapepala, nsalu, zodzoladzola ndi zina zambiri chifukwa cha zinthu zake zabwino kwambiri.

Sera ya polyethylene imakhala ndi kukhazikika kwa mankhwala, makina abwino kwambiri, mphamvu zamagetsi, kubalalitsidwa, fluidity, demoulding, high softening point, low viscosity kusungunuka, kuuma kwakukulu ndi kukana kwabwino kuvala. Amagwiritsidwa ntchito pokonza pulasitiki wamba monga dispersant a masterbatches osiyanasiyana, demoulding wothandizira kwa polyolefin processing, lubricant kwa polychlorethylene processing pulasitiki, etc. Gawo la sera la polyethylene lakulitsidwa kukhala mapulasitiki auinjiniya omwe ali ndi zofunikira pakuchita bwino komanso kukula mwachangu.
M'kati mapulasitiki processing, pe sera angagwiritsidwe ntchito ngati dispersant a masterbatch zosiyanasiyana, processing lubricant mapulasitiki osiyanasiyana ndi comptibilizer nkhuni pulasitiki gulu. Ndiwothandizira wamba mumakampani opanga mapulasitiki.
Masterbatch dispersant
Ndi chitukuko cha makampani pulasitiki, makampani processing pulasitiki mochulukira amakonda kugwiritsa ntchito zosiyanasiyana yabwino zinchito masterbatch kuchepetsa mtengo wa zopangira, ndondomeko ndalama, kukonza bwino kupanga, kupereka katundu osiyanasiyana mankhwala pulasitiki, kuti akwaniritse. zosowa zosiyanasiyana za msika.
Pulasitiki masterbatch makamaka imaphatikizapo kudzaza masterbatch, lubricating masterbatch, transparent masterbatch, pearlescent masterbatch, color masterbatch ndi antistatic masterbatch. Pulasitiki masterbatch imakonzedwa ndikuwonjezera zowonjezera pulasitiki kupitilira kuchuluka kwanthawi zonse mu utomoni wonyamulira, kotero masterbatch ikhoza kuwonjezeredwa mwachindunji pakuumba zinthu zapulasitiki.
Sera ya polyethylene itha kugwiritsidwa ntchito ngati dissperant of thermoplastic resin masterbatch ndi mafuta opaka mafuta kuti mudzaze masterbatch ndi degradation masterbatch. Sera ya polyethylene imagwirizana bwino ndi pulasitiki, kukana kutentha kwabwino, katundu wosakaniza bwino ndi kuphwanya kosavuta, zomwe sizimakhudza ntchito ya mapeto; Zimagwira ntchito yabwino pakunyowetsa, kufalitsa ndi kukhazikika kwa tinthu tating'onoting'ono ta filler kapena pigment. Kafukufuku wasonyeza kuti polymerized polyethylene sera ndi bwino kuposa losweka polyethylene sera mwa mawu a onse kupezeka mphamvu ndi matenthedwe bata la filler ndi pigment particles. Chifukwa chake, sera yopangidwa ndi polyethylene imagwiritsidwa ntchito kwambiri pazinthu zapamwamba za masterbatch, monga pe sera SN118 ndi SN119 ya Qingdao Sainuo, yomwe imakhala ndi kubalalitsidwa bwino komanso kukhazikika kwamafuta mu masterbatch.

Mafuta opangira mapulasitiki
Mafuta omwe amagwiritsidwa ntchito pokonza mapulasitiki ndikuwongolera kutulutsa ndi kutsitsa kwa mapulasitiki, makamaka thermoplastics. Ntchito yaikulu ya lubricant ndi kuchepetsa mkangano pakati pa zipangizo pulasitiki ndi processing makina ndi pakati zipangizo pulasitiki ndi mamolekyu mkati mkati processing, kuti patsogolo processing ntchito mapulasitiki ndi kusintha ntchito mankhwala.
Malinga ndi momwe mafuta amagwirira ntchito pokonza pulasitiki, mafutawo amagawidwa kukhala mafuta amkati ndi mafuta akunja. Mafuta amkati amakhala ndi mgwirizano wina ndi polima, ndipo zotsatira zake zokometsera ndizochepetsa kukangana pakati pa mamolekyu a polima kapena mphamvu pakati pa mamolekyu a polar polima. Kunja mafuta makamaka kuchepetsa mkangano pakati polima ndi processing makina, amene angathe kusintha ntchito yaitali, dimensional bata, kupewa makulitsidwe ndi kuonjezera kupanga mphamvu. Pali mitundu yambiri yamafuta odzola, ambiri mwa iwo amakhala ndi mafuta mkati ndi kunja. Yokhala ndi mafuta amphamvu kwambiri imatchedwa mafuta akunja, ndipo yomwe ili ndi mafuta amphamvu mkati imatchedwa mafuta amkati.
Mafuta ambiri amagwiritsidwa ntchito, monga okhwima PVC, polyolefin, polystyrene, ABS, phenolic utomoni, melamine utomoni, mapadi acetate, unsaturated poliyesitala, polyamide, mphira ndi zinthu zina processing adzagwiritsa ntchito lubricant. Koma ntchito yayikulu yamafuta akadali mu PVC yolimba, kotero powunika momwe mafuta amagwirira ntchito, anthu nthawi zambiri amangoyang'ana PVC yolimba.
PVC lubricant
PVC utomoni ali katundu kwambiri thupi ndipo akhoza kupangidwa okhwima ndi kusinthasintha zinthu. Njirayi imaphatikizapo extrusion, kupaka, jekeseni, kuumba nkhonya ndi calendering. The mankhwala monga mapaipi, mbiri, mapepala, mankhwala dzenje, waya ndi chingwe m'chimake, etc. PVC utomoni ali osauka matenthedwe bata, choncho ayenera kuwonjezera kutentha stabilizer ndi lubricant pa processing. Mafuta amatha kuletsa utomoni kukhalabe mu extruder kapena kuwola chifukwa cha kutenthedwa komweko, ndikupangitsa utomoni kukhala wosavuta kupanga. Mbiri PVC chimagwiritsidwa ntchito mbiri zokongoletsa mkati, kumanga madzi ndi mipope ngalande ndi kusonkhanitsa zitseko pulasitiki zitsulo ndi windows.Plastic mbiri wapangidwa ndi PVC ndi mitundu yoposa khumi zowonjezera pulasitiki ndi kusakaniza kusinthidwa ndi extrusion. Lubricant ndi chowonjezera chofunikira.

Sera ya polyethylene imagwiritsidwa ntchito kwambiri popaka mafuta akunja, ndi mafuta akunja amphamvu. Lilinso ndi lubricity wabwino pakati ndi kenako magawo akamaumba. Itha kuonedwa ngati mafuta apakati komanso apakatikati, ndipo ndi oyenera kupanga zinthu zomwe zimakhala ndi gawo lalikulu. Itha kugwiritsidwa ntchito osati mu dongosolo lokhazikika la mchere wotsogola, komanso mu dongosolo lokhazikika la calcium zinki lopanda poizoni komanso dongosolo losakhazikika lapadziko lapansi. Mwachitsanzo, Qingdao Sainuo a SN3316, SN9126, SN9130 ndi lubricity kwambiri, amene angagwiritsidwe ntchito mitundu yosiyanasiyana ya PVC luso processing, makamaka PVC calendering ndi extrusion ndondomeko, amene akhoza kwambiri kusintha plasticization wa PVC ndi kusintha mphamvu makina mankhwala; Amagwiritsidwa ntchito pokonza zinthu zolimba kutentha kwambiri, ndipo ali ndi anti adhesion ndi anti-ssrch properties. Oxidized sera ufa zimagwiritsa ntchito ngati lubricant kunja kwa zolimba ndi zofewa PVC processing, amene akhoza kusintha makokedwe, kuchepetsa mpweya wa organotin ndi kutsogolera mchere dongosolo khola, ndipo ali mkulu kondomu kunja ndi zotsatira demoulding, popanda kukhudza Vicat kutentha kusintha kutentha ndi zotsatira zake. mphamvu ya mankhwala.
Qingdao Sainuo Chemical Co., Ltd. Ndife opanga sera ya PE, sera ya PP, sera ya OPE, sera ya EVA, PEMA, EBS, Zinc / Calcium Stearate …. Zogulitsa zathu zadutsa kuyesa kwa REACH, ROHS, PAHS, FDA.
