Pali kusiyanitsa kwapamwamba komanso kotsika kwazinthu zilizonse, kupatula matumba athu oluka a PP, chifukwa pali mpikisano, pali chiyeso cha phindu.Ndiye ndingagule bwanji matumba a PP okhala ndi zabwino pamsika wovutawu?
Choyamba, kuchokera ku maonekedwe a chikwama cholukidwa.
Njira yoyamba yosiyanitsa ubwino wa matumba oluka ndi maonekedwe.Waukulu zopangira matumba nsalu ndi polyethylene ndi polypropylene, amene amapangidwa kudzera mndandanda wa extrusion, nsalu, kusindikiza ndi thumba kusoka etc..The matumba nsalu opangidwa kuchokera zinthu koyera zambiri chiwalitsiro mandala ndi kumva bwino popanda burring.Mlingo waukadaulo udzawonetsedwa mwachindunji pamawonekedwe.
Kachiwiri, kuchokera m'manja kumva thumba loluka.
Kupatula kuyang'ana mwachidziwitso, kungathenso kudziwika ndi manja.Matumba owongoka okhala ndi zida zokongola komanso kapangidwe kabwino nthawi zambiri amakhala wandiweyani, ofewa komanso opaka mafuta, ndipo kulimba kwawo kokwanira sikudzachepetsedwa, kuwapanga kukhala zosankha zabwino m'magawo osiyanasiyana.Matumba olukidwa okhala ndi zida zosauka komanso kapangidwe kake ndi operewera.Izi zitha kudziwikanso mosavuta.
Chachitatu, kuchokera ku mapangidwe a PP matumba.
Nthawi zambiri, kachulukidwe, misa pagawo lililonse komanso kukhathamiritsa kwa thumba loluka kumatha kuwonedwa ngati kukonza kwapamwamba kuli bwino komanso kofananira, zomwe zingakhudze kugwiritsa ntchito thumba loluka. kukhala akatswiri.
Inde, opanga masiku ano ali ndi matekinoloje osiyanasiyana.Posankha ndi kuzindikira matumba nsalu, tiyenera kusamala za kupanga ndi processing umisiri ndi ndondomeko ndondomeko ya opanga osiyanasiyana.Tiyenera kusankha zikwama zoluka zokhala ndi zotsimikizika kuti zizigwiritsidwa ntchito motetezeka komanso mokhazikika.
Zinthu ziwiri zofunika kwambiri:
1.Sankhani wopanga/wopereka wabwino:fakitale ina yayikulu yotamandidwa ndi anthu ili ndi kuwongolera kwabwino kwambiri popanga chikwama cholukidwa, ukadaulo wopanga komanso njira yopangira ndizovuta kwambiri.Kuwongolera khalidwe lawo ndi zofunikira zopanga, kuyang'anira kuli mulingo wapamwamba kwambiri.Ena aiwo amathanso kuwonetsetsa kuti miyezo yaumoyo ndi yabwino.
2.Musasankhe mtengo womwe ndi wotsika kwambiri:Ngati thumba la PP lili ndi khalidwe lofanana, mitengo yawo idzakhala yofanana, ngati kugula kwanu kuli kwakukulu kwambiri komanso mgwirizano wautali, kuchotsera pang'ono kungaperekedwe, ngati mungasankhe mtengo womwe uli wotsika kwambiri kuposa wamba, ndiye kuti thumba. Ubwino ndiwotsikanso kuposa wanthawi zonse, chifukwa kutulutsa chilichonse kumafunikira mtengo wake, mtengo wotsika umatanthauza mtengo wotsika, mtengo wotsika umatanthauza kutsika, musasankhe mtengo ndi wotsika kwambiri, apo ayi simupeza mtundu womwe mukufuna.
