Kusanthula kwathunthu kwa thovu la EVA: kosavuta kumva, kukulolani kukhala katswiri!#makina otulutsira thovu #kutulutsa pepala la thovu #mzere wotulutsira filimu wa eva

Zizindikiro za magwiridwe antchito a EVA nthawi zambiri zimaphatikizapo izi: kuuma, mphamvu yokoka, kutalika, mphamvu yokoka, mphamvu yong'ambika, kusintha kosatha kwa compression, ndi kusinthasintha.

01.kuuma

Aliyense akudziwa zimenezo. Kulimba ndi kuuma kwa chinthucho kungayesedwe pogwiritsa ntchito njira yoyezera kuuma kwa Shaw. Thovu la EVA kutentha kungakhale kuyambira madigiri 10 mpaka madigiri 80.

02.Kunenepa

Anthu ambiri amatha kuyesa kuyeza pogwiritsa ntchito zida zosavuta. Nthawi zambiri, zonse zimagwiritsa ntchito microcomputer specific gravity balance. Chiŵerengero chochepa cha zinthu zomwe ndimagulitsa chikuwoneka kuti ndi pafupifupi 0.05 (g / cm³).

03. Kukulitsa

Kutalikitsa nthawi yopuma. Pangani zinthu zopangira thovu za EVA m'njira zina, monga 60 * 10 * 5mm, kenako gwiritsani ntchito makina oyesera kukoka pa liwiro losasintha, kutalika kwa kusweka kugawidwa ndi kutalika koyambirira. Mphamvu ya kupsinjika, mwachidule, ndi katundu panthawi yosweka. Ndipo muyeso wa kutalikitsa liwiro lolumikizana. Mphamvu ya kung'amba, yomwe ndizovuta kufotokoza. Ndi kupanga chidutswa cha EVA kukhala pakamwa kakang'ono, mbali ziwiri za pakamwa zokhazikika mu zolumikizira ziwiri za makina oyesera kupsinjika, zololedwa pambuyo pake kuti zikoke. Katundu wolandiridwa ndi mphamvu ya kung'amba.

04. Kupindika kosatha kopanikizika

Pangani EVA mu chidutswa chozungulira chomwe chatchulidwa ndikuchiyika mu compression tilt, sinthani ku magawo ofunikira, kenako muyike mu makina okalamba kwa maola angapo. Pomaliza, imachotsedwa kuti iyese makulidwe a circle sheet. Mtengo wowerengedwa ndi ma coefficients angapo ndi compression.

05. Kutanuka

Ili ndi dzina losamveka bwino. Tiyerekeze kuti ili limatchedwa kulimba mtima, silikuwoneka lokwanira. Ngati mukufuna kunena kuti chithunzicho chingatchedwe kugonana kwa Q. Mitundu ina ili ndi dzina laukadaulo, kulimba kwake kumagawidwa m'magawo awiri: buffer ndi reverse hair. Mawu awiriwa ayenera kumveka bwino. Sindidzalankhulapo.

Kuchuluka kwa thovu pang'ono pakapita nthawi yayitali popanda kuchuluka kudzawonjezeka, izi sizoyenera kukonza. Kudalira dongosolo loyenera popanga zinthu. Zipangizo zonse ndizabwino, paki siyenera kupitirira sabata imodzi, kusiyana kuyenera kugwiritsidwa ntchito mkati mwa masiku atatu, kotero sikungapangitse kuti kuchulukitsa kuchuluke. Pambuyo pa nthawiyi, ikhoza kubwereranso ku uvuni kuti ipange tirigu, kuwonjezera DCP koyenera.

Pa thovu laling'ono, malo ena okhuthala okhala ndi mabowo amatha kuwonjezera nthawi yotulutsa thovu, kapena kuwonjezera kutentha kwa nkhungu, kapena kuwonjezera kuthamanga kwa makina; pa fomula, DCP ikhoza kuwonjezeredwa moyenera, kapena chothandizira cholumikizira chingawonjezedwe.

Zowonjezera zowonjezera ku mawonekedwe a thovu la EVA

01.kuchotsedwa

Border imapangidwa kukhala chinthu chopangidwa pambuyo pa zinthu zina zosafunikira, mchira, m'mphepete ndi zina. Zonse ndi zotupa kwambiri. Zinthu zamtunduwu zimawononga ndalama zambiri, zomwe zimachepetsa kwambiri ndalama zopangira, ndithudi, zimathanso kubweretsa zotsatirapo zakuthupi. Pafupifupi mitundu yonse ya EVA yochita izi ikugwiritsidwa ntchito, kotero sindibwerezanso.

02. Wothandizira wosasunthika

Zinthu zina zimafunika kuti zikhale ndi ntchito yoletsa kusinthasintha kwa kutentha, ndipo zinthu zopangira thovu la EVA zokha zimakhala ndi mphamvu yamagetsi, kotero muyenera kuwonjezera zina zoletsa kusinthasintha kwa kutentha mu fomula. Choletsa kusinthasintha kwa kutentha chomwe chimagwiritsidwa ntchito mu EVA ndi chosakaniza, gawo lenileni la MS ndi lovuta kwambiri, sindinkadziwa panthawiyo, mlingo wake ndi 3% -5%.

03.Kuzimitsa moto

Zinthu zopangira thovu la EVA Zogwiritsidwa ntchito ngati zinthu zina zopakira zimatha kukhala zoletsa moto. Choletsa moto chikhoza kuwonjezeredwa bwino mu fomula kuti chikwaniritse zotsatira za choletsa moto. Choletsa moto chomwe chimagwiritsidwa ntchito kwambiri mu pulasitiki Mg (OH) 2, Al (OH) 3, chimakhudzanso zinthu zotulutsa thovu la EVA, koma mlingo wake ndi waukulu, timagwiritsa ntchito 12% -20%, koma pazofunikira za choletsa moto pazinthu zambiri, sizosavuta kugwiritsa ntchito.

04. Chomera chokhwima msanga

Njira yopangira thovu la EVA imatenga nthawi. Ngati mukufuna kuwonjezera zokolola ndikuchepetsa mphamvu zomwe zimagwiritsidwa ntchito, chopangira ...

05. Chopaka utoto

Zinthu zopangidwa ndi thovu nthawi zambiri zimakhala ndi utoto, kotero muyenera kuwonjezera chopaka utoto mu fomula kuti musinthe mtundu. Kusakaniza mitundu ya zinthu zopangidwa ndi thovu la EVA kungagwiritsidwe ntchito ndi toner, guluu wamtundu, ndithudi, ndi bwino kugwiritsa ntchito tinthu tating'onoting'ono ta mtundu. Zinthu zopangidwa ndi MS sizingakhale mtundu wa kompyuta, mwina chifukwa chinthucho chisanafike komanso chitatha mtundu chimasintha kwambiri.
