Sera imatha kugwira ntchito munjira zonse zochiritsira zokutira ufa. Kaya ikutha kapena kuwongolera filimuyo, mudzaganiza zogwiritsa ntchito sera poyamba. Inde, mitundu yosiyanasiyana ya sera imagwira ntchito zosiyanasiyana popaka ufa.

sera ya PE ufa

Ntchito ya sera mu kupaka ufa
Sera imagawidwa mu mawonekedwe a emulsion, flake ndi sera ya micronized. Pali phula loyera lachilengedwe, sera yosinthidwa yachilengedwe, sera yopangidwa ndi theka, sera yopangira, ndi zina zambiri. Imagwiritsidwa ntchito kwambiri posintha polima ndi sera yopangira, ndipo ndi yolimba. Monga polyolefin sera, ndi polytetrafluoroethylene sera (PTFE sera), etc.
Komabe, maonekedwe ake mu ❖ kuyanika akhoza pafupifupi ogaŵikana m'magulu atatu otsatirawa:
1. chisanu zotsatira: pamene kusungunuka kwa sera anasankha ndi otsika kuposa kuphika. kutentha, sera amasungunuka mu madzi pa kuphika, ndipo pambuyo filimu utakhazikika, wochepa thupi wosanjikiza wa chisanu ngati aumbike pa ❖ kuyanika pamwamba.
2. Mpira kutsinde zotsatira: zotsatira zake ndi kuti sera ndi poyera tinthu kukula pafupi kapena zazikulu kuposa ❖ kuyanika filimu makulidwe, kotero kuti zikande kukana ndi zikande kukana sera akhoza kuwonetsedwa.
3. Zotsatira zoyandama: mosasamala kanthu za mawonekedwe a sera, sera imayandama pamwamba pa filimuyo panthawi yopanga filimuyo ndipo imamwazika mofanana, kotero kuti pamwamba pa filimuyo amatetezedwa ndi sera ndikuwonetsa makhalidwe a sera.
4. Kuwongolera kusalala kwa ufa
Kwenikweni,
Sera ya polyethylene ya zokutira ufa wa Sainuo
1. Kwa utoto, zodzaza zimakhala ndi zobalalika zabwino.
2. Kusanja bwino.
3. Palibe chikasu.
4. Kukana kukanda, kuuma kwakukulu, kufalikira kwabwino, komanso kufalikira kwabwino pazaza zodzaza pigment.
5. Kuwala kwa gloss
6. kukana kwa mankhwala
Chifukwa cha kuyandama kwa sera, phula lopangidwa ndi mafuta osakanikirana limapangidwa pamwamba pa zokutira, kotero kuti madzi otentha amatsutsana ndi bwino, ndipo kukana kutsitsi kwa mchere kumakhala kopambana.
7. Valani kukana, zikande kukana
Sera imagawidwa pamwamba pa filimu kuti ateteze filimuyo, kupewa zokopa, komanso kupereka kukana kuvala. Sera yosinthidwa ndi propylene ndi sera ya polytetrafluoroethylene nthawi zambiri imawonjezeredwa, yomwe imakhala yothandiza kwambiri pakupanga ndege yakuda ndi mchenga wonyezimira wochepa.
8. Control friction coefficient
Nthawi zambiri, sera yotsika kwambiri ya sera imagwiritsidwa ntchito kuti filimuyo ikhale yosalala bwino. Panthawi imodzimodziyo, imakhala ndi kukhudza kofewa kwapadera kwa silika chifukwa cha mitundu yosiyanasiyana ya sera. Mofananamo, chifukwa chosanyowa kwa zokutira zina, zokutira zotsutsana ndi kuipitsa zimatha kukonzedwa. M'malo mwake, poganizira kukonzanso katundu wa kupaka ufa, ngati pamwamba sikophweka kunyowa, ufa siwophweka ufa.
8. Control friction coefficient
Nthawi zambiri, sera yotsika kwambiri ya sera imagwiritsidwa ntchito kuti filimuyo ikhale yosalala bwino. Panthawi imodzimodziyo, imakhala ndi kukhudza kofewa kwapadera kwa silika chifukwa cha mitundu yosiyanasiyana ya sera. Mofananamo, chifukwa chosanyowa kwa zokutira zina, zokutira zotsutsana ndi kuipitsa zimatha kukonzedwa. M'malo mwake, poganizira kukonzanso katundu wa kupaka ufa, ngati pamwamba sikophweka kunyowa, ufa siwophweka ufa.
9. Chepetsani tinthu ting’onoting’ono ndi kukana zidindo za zala
Anthu ali ndi mavuto otsatirawa popanga zitsulo zokhala ndi ufa, ufa wa ngale ndi zina:
(1) Ufa wachitsulo ukachuluka, ufawo umakhala ndi tinthu ting’onoting’ono ndipo ndalama zolipiridwazo zimachepa. Pambuyo powonjezerapo positi yosakanikirana sera, izi zidzasintha kwambiri.
(2) Chifukwa mawonekedwe a siliva wonyezimira amakhudzidwa ndi thukuta la dzanja la munthu atagwiritsidwa ntchito kwa nthawi yayitali, amatha kuwala, ndipo zidindo za zala pamwamba sizingachotsedwe. Pambuyo powonjezera pang'ono ufa wa sera ndikusakaniza, zidzakhala bwino.
10. Chowonjezera chopyapyala chapamwamba
Chophimba cha ufa wa ultrafine ndi woonda, womwe umakhala ndi chiyembekezo chowala. Koma kwa osakhala ofanana kutsitsi ndi osauka ufa chiŵerengero, ufa Mumakonda mlingo akhoza kukhala bwino powonjezera zina zapadera, makamaka homogeneity wa coarse ndi ufa ufa. Chowonjezera ichi ndi kagawo kakang'ono ka ufa wapadera wa sera womwe umayikidwa pazitsulo zomwe zilipo kale (monga alumina, etc.).

Sanding
12. Kugwiritsa UV kuchiritsa ufa ufa.
Pamene sera ya 4.0% ya PTFE ikuwonjezeredwa ku ndondomekoyi panthawi ya kuchiritsa kwa UV, gloss ya filimuyo idzachepetsedwa kufika 19, ndipo filimu yokhala ndi tirigu wobiriwira imatha kupezeka.

The koyambirira ntchito sera mu ❖ kuyanika ufa ndi kusintha pamwamba zimatha filimu, makamaka kuwongolera kusalala, zikande kukana ndi madzi filimu. Pambuyo pake, idagwiritsidwa ntchito kukhudza mawonekedwe a rheological of zokutira, monga degassing, kuwongolera kusanja ndi kutha, komanso kusintha mawonekedwe a zokutira. Tsopano, anthu amasamalira kwambiri sera ndi kuphatikiza kwa magwiridwe antchito ambiri. Chikoka cha sera pamakina omangira komanso kusinthidwa kwa filimuyi kwadzutsanso chidwi chachikulu.
Ndi chitukuko chosalekeza cha kafukufuku wopaka ufa, anthu adzakhala ndi chidziwitso china cha sera. Sera idzagwiritsidwa ntchito kwambiri popaka ufa.
Ntchito zazikulu za zowonjezera ufa wa sera ndi: kuonjezera kuuma kwa ❖ kuyanika, kuvala kukana, kupukuta, kutayika, kupititsa patsogolo kutulutsa bwino, etc. Phula la sera lomwe limagwiritsidwa ntchito popaka ufa limagawidwa mu sera ya polyethylene, polypropylene sera, polytetrafluoroethylene sera, polyamide sera, etc. Pankhani yofananira komanso mtengo wake, sera ya polyethylene ndiyabwino ndipo imatha kukwaniritsa zofunikira zonse pakuumitsa ndi kukana kukanika, chifukwa chake imakhala ndi mawonekedwe osiyanasiyana. Pankhani yowumitsa ndi kukana kukana, sera ya PTFE ndi yabwino kwambiri, ndipo mtengo ulinso pamtunda wapamwamba.
Kuphatikiza pakuumitsa kulimba komanso kukana kukanda, ufa wina wa sera umakhalanso ndi gawo lina la matting. Mwachitsanzo, sera ya polypropylene ingagwiritsidwe ntchito ngati cholowa m'malo mwa zomatira mu zokutira zaufa zomwe zili ndi zofunika zochepa pakukweza. Komabe, panthawiyi, mlingowo umaposa 2%, ndipo nthawi zina pamakhala tinthu tating'ono ta sera tomwe timatuluka mufilimuyo.
Pogwiritsira ntchito, ufa wa sera umakhala wambiri, ndipo palinso njira ziwiri zogwiritsira ntchito: kuwonjezera ndi kusakaniza positi. Sera yosakanizidwa ndi sera yaying'ono yokhala ndi tinthu tating'onoting'ono, ndipo tinthu tating'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'ono ting'ono ting'ono ting'ono ting'ono ting'ono ting'ono ting'ono ting'ono ting'ono.
Kupanga polyethylene sera ndi zosakwana 1% akhoza ziwonjezeke ndi mawotchi kuvala akhoza kuchepetsedwa pamene extrusion. Makamaka pankhani ya ufa wabwino kwambiri, zotsatira zake zimakhala zoonekeratu.
