polyethylene sera , yomwe imadziwikanso kuti sera ya polima, imatchedwa sera ya polyethylene mwachidule. Ili ndi kukana kozizira kwambiri, kukana kutentha komanso kukana kwamankhwala. Monga chowonjezera chowonjezedwa mwachindunji pakukonza kwa polyolefin pakupanga wamba, kumatha kukulitsa kukongola komanso kukonza magwiridwe antchito azinthu. Monga mafuta,pe sera limakhala ndi mankhwala okhazikika komanso magetsi abwino.

Njira yopangira pe sera

Sera ya polyethylene imatha kupangidwa m'njira zinayi: Ndi njira yosungunula, njira ya emulsification, njira yobalalika ndi njira ya micronization.
1. Njira
yosungunulira
2. Njira ya emulsification:
Kugwiritsa ntchito njira iyi kutulutsa sera ya polyethylene ingapeze tinthu tating'onoting'ono tating'onoting'ono, tomwe tingakhale tambiri tambiri tambiri tambiri tambiri tambiri tamadzi, koma chovuta ndi chakuti surfactant idzakhudza kukana kwamadzi kwa filimuyo.
3. Njira yobalalitsira:
Powonjezera sera ku yankho ndiyeno kulibalalitsa ndi zipangizo zobalalitsira, khalidwe la mankhwala ndi lochepa ndipo mtengo wake siwotsika, choncho sichivomerezeka.
4. Njira ya Micronization:
Njirayi imapangidwa ndi kugundana pakati pa sera yaiwisi yaiwisi, pang'onopang'ono kupanga tinthu tating'onoting'ono, kuyang'ana ndi mphamvu ya centrifugal molingana ndi kusiyana kwa khalidwe, ndipo potsiriza kusonkhanitsa. Iyinso ndiyo njira yomwe imagwiritsidwa ntchito kwambiri popanga pano.
Ambiri kupanga njira polyethylene sera monga mkulu-anzanu ndi otsika-anzanu polymerization. Sera yomwe imapezeka pansi pa kupanikizika kwambiri imakhala ndi unyolo wa nthambi ndi malo otsika osungunuka. Ngakhale sera yomwe imapezeka pansi pa kupanikizika kochepa imakhala yovuta, imakhala yochepa pang'ono posalala.
Makhalidwe akuluakulu a pe sera
Imakhala ndi kukhuthala kochepa, kufewetsa kwambiri, kuuma kwabwino, kosakhala ndi poizoni, kukhazikika kwamafuta, kutsika kwa kutentha kwapamwamba, kubalalitsidwa kwamitundu, kununkhira bwino kwakunja komanso kuthirira mwamphamvu mkati, komwe kungapangitse kupanga bwino kwa processing pulasitiki, zabwino chinyezi kukana kutentha firiji, mphamvu kukana mankhwala ndi ntchito kwambiri magetsi, ndipo akhoza kusintha maonekedwe a zinthu zomalizidwa.

Makampani ogwiritsira ntchito sera
1. Zopaka m'madzi
Kuonjezera sera ya polyethylene emulsion ku utomoni wa acrylic kungapangitse hydrophilicity yake, kuteteza kutsetsereka, kuteteza kumamatira ndi kukana madontho. Sera ya Pe imatha kutulutsa zotsatira zofananira monga kukana kuvala ndi kukana kukanika, kuchepetsa kugundana kwa malo okutira, ndikupangitsa kuti chizolowezi choterera chikhale chachikulu kuposa chizolowezi chokanda pamene chinthucho chikukhudzana ndi zokutira. Kusamuka kwa polyethylene sera ufa kupita pamwamba ❖ kuyanika kungachepetse kwambiri mikangano yamphamvu ya ❖ kuyanika pamwamba. Kuonjezera sera ya polyethylene ufa ku zokutira kungachepetse kwambiri chizolowezi chopaka kuti chipukutidwe ndi kukangana, kuti chikhale cholimba cha gloss yochepa. Sera ya polyethylene ili ndi zowonekeratu kuzimiririka kwa zokutira za poliyesitala. Kuphatikiza apo, sera ya polyethylene imagwiritsidwanso ntchito ngati njira yosinthira kusungunuka kwa zokutira za ufa.
2.
Sera ya
3. Colour masterbatch
Pe sera imayenderana bwino ndi tona, ndiyosavuta kunyowetsa pigment, ndipo imatha kulowa mkati mwa pores mkati mwa pigment aggregate kuti ifooketse mgwirizano, kuti mtundu wa pigment ukhale wosavuta kusweka ndi mphamvu yakumeta ubweya wakunja, kumene kwaiye particles angathenso mwamsanga wetted ndi kutetezedwa. Chifukwa chake, itha kugwiritsidwa ntchito ngati dispersant ndi kudzaza masterbatch yamitundu yosiyanasiyana ya thermoplastic resin colorbatch, Lubricating dispersant yoyipitsa masterbatch. Komanso, polyethylene sera akhoza kuchepetsa mamasukidwe akayendedwe a dongosolo ndi kusintha fluidity. Chifukwa chake, kuwonjezera sera ya polyethylene popanga mtundu wa masterbatch kumatha kupititsa patsogolo magwiridwe antchito ndi zokolola komanso kukhazikika kwa kubalalitsidwa.
4. Kusindikiza inki
Polyethylene sera angagwiritsidwe ntchito polyethylene filimu, polypropylene filimu, chinyezi-umboni cellophane, pulasitiki ndi ma CD zipangizo za zipatso shuga, mkaka, madzi a zipatso, mankhwala chisamaliro khungu, mabotolo mankhwala, zotsukira ndi chakudya, komanso inki. pazifukwa zina, monga inki yochotsera. Zimakhala ndi zotsatira zabwino ngati inki kuvala zosagwira wothandizira. The tinthu kukula kwa polyethylene sera palokha ndi pafupi kapena wamkulu pang'ono kuposa makulidwe a inki filimu, choncho poyera, kusonyeza zikande kukana ndi zikande kupewa makhalidwe sera. Pa nthawi yomweyo, polyethylene sera akhoza kupanga yunifolomu filimu pamwamba filimu kuteteza inki pamwamba.
5. Penti yolembera misewu
Pambuyo sera ya polyethylene yapangidwa kukhala kubalalitsidwa kwa toluene ndikuwonjezeredwa mu utoto, kuwala kumasunthira pamwamba pa zokutira kenako ku polyethylene sera ufa. Kupyolera mu refraction ndi kufalikira kwa ufa, kunyezimiritsa kwa kuwala kuwonetsera pa ❖ kuyanika pamwamba pa njira yomweyo kufooka, kuti akwaniritse kutha. Kutha kwa sera ya polyethylene yokhala ndi kukula kosiyanasiyana ndi mitundu ndi yosiyana. Pakugwiritsa ntchito kwenikweni, mlingo wake ukhoza kusinthidwa malinga ndi zosowa.
6. Kupaka utoto wa pulasitiki
Monga dispersant pigment popaka utoto wa pulasitiki, sera ya polyethylene imakhala ndi mawonekedwe ogwirizana bwino ndi kukana kutentha ndi mapulasitiki, kusakaniza bwino ndi inki, kuphwanya kosavuta, ndipo sikumakhudza mtundu wa zinthu zowonongeka. Sera ya polyethylene imatha kubweretsanso mtengo womwewo pamtunda wa pigment particles. Zochokera amuna kapena akazi okhaokha repulsion mfundo, particles sadzakhala kukopa kapena aggregate mzake, kuti tikwaniritse yunifolomu kubalalitsidwa kwa pigment.
