Pali mitundu yambiri yamafilimu obiriwira, ndipo mafilimu obiriwira osiyanasiyana ali ndi ntchito zosiyanasiyana. Kuphatikiza apo, makulidwe a filimu yowonjezera kutentha kumakhala ndi ubale wabwino ndi kukula kwa mbewu. Kanema wowonjezera kutentha ndi pulasitiki. M'chilimwe, filimu yowonjezera kutentha imadziwika ndi dzuwa kwa nthawi yayitali, ndipo ndikosavuta zaka zambiri, ndipo ndizosavuta, zomwe zimakhudzananso ndi makulidwe a wowonjezera kutentha. Ngati filimu yowonjezera kutentha ndiyandiweyani, idzapangitsa kuti chochitika chikhale chovuta, ndipo ngati wowonjezera kutentha ndi wochepa thupi, sutha kuchita mbali yabwino yamagetsi. Kuphatikiza apo, makulidwe a filimu yobiriwira imagwirizananso ndi mtundu wa mbewu, maluwa, ndi zina zambiri.
Kodi mafilimu obiriwira obiriwira ndi angati? Makanema obiriwira obiriwira nthawi zambiri amagawika kukhala koorninghouse filimu, pea wowonjezera kutentha, eva wowonjezera kutentha filimu, ndipo molingana ndi zomwe zili mogwirizana ndi nkhaniyi.
POBOOo Ili ndi mphamvu yayikulu, mphamvu yabwino yamafuta, ndipo imatha kuteteza kukula kwa mbewu. Mphamvu ya Tunsile imatanthawuza kuti kanema waulimi akuyenera kukokedwa mwamphamvu pophimba. Ngati mphamvu za tansile sizabwino, ndizosavuta kung'ambika, kapena ngati sizing'ambika panthawiyo, mphepo yamphamvu nthawi zina idzawononga filimu yaulimi. Kutulutsa kwamitundu yabwino ndikofunikira kwambiri pazomera. Kuwongolera ndi chinyezi kuwongolera mkati mwa kanema waulimi ndi kosiyana ndi chilengedwe kunja kwa filimu yobiriwira. Chifukwa chake, kanema waulimi amakhala ndi kutentha kwabwino komanso chinyezi kumawongolera, chomwe ndi chothandiza kwambiri kukula kwa mbewu ndipo umakondedwa kwambiri ndi anthu.
Pen pezani filimu yowonjezera: Phunzi filimu ndi mtundu wa filimu ya polyethylene yaulimi, ndipo perinion ya polyethylene. Polyethylene ndi mtundu wa pulasitiki, ndipo thumba la pulasitiki lomwe timagwiritsa ntchito ndi mtundu wa PIP PLAP CAPTO. Polyethylene ali ndi bata labwino kwambiri la mankhwala. Polyethylene ndiosavuta kukhala Photo-oxidid, oxidid oxidid, ndi ozoni owopera, ndipo ndikosavuta kunyoza ma ray a ultraviolet. Carbor wakuda ali ndi mphamvu yowala kwambiri pa polyethylene.
Eva wowonjezera filimu: Chithunzi cha Eva chimanena za chojambulachi chopangidwa ndi a ALTHLENE-vinyll Acetate CAPACHER ndiye nkhani yayikulu. Makhalidwe a Eva Ammicructur filimu ndi madzi abwino kukana, kukana bwino kuwononga, komanso kuteteza kwambiri.
Kukaniza kwamadzi: Osatengera njira, chinyezi-chinyezi, madzi abwino kukana.
Kukana Kukula: Kugwiritsa ntchito madzi am'madzi, mafuta, alkali, ndi mankhwala osokoneza bongo, antibacterion, opanda poizoni, wopanda mphamvu, wopanda pake.
Kutulutsa kwamafuta: kutentha kukumba, kuteteza bwino kwambiri, kutetezedwa kozizira, komanso kutentha kochepa, ndipo amatha kupirira kutentha kozizira komanso dzuwa.
Kodi mungasankhe bwanji makulidwe a wowonjezera kutentha? Makulidwe a filimu yowonjezera kutentha imakhala ndi ubale wabwino ndi kuunika kopepuka komanso ali ndi ubale wabwino ndi moyo wautumiki wogwira mtima.
Nthawi Yogwiritsa Ntchito: Miyezi 16-18, makulidwe a 0.08-0.10 MM ndiyofunika.
Nthawi Yothandiza: Miyezi 24-60, makulidwe a 0.12-0.15 mm ndizovuta.
Kukula kwa filimu yomwe imagwiritsidwa ntchito m'matumbo obiriwira ambiri kumafunikira kupitirira 0,15 mm.
