Pakalipano, matumba apulasitiki omwe amagulitsidwa pamsika amagawidwa m'magulu atatu mwazinthu zopangira: gulu loyamba ndi polyethylene, yomwe imagwiritsidwa ntchito makamaka kunyamula zipatso ndi ndiwo zamasamba wamba;gulu lachiwiri ndi polyvinylidene kolorayidi, amene makamaka ntchito yophika chakudya., Ham ndi zinthu zina;gulu lachitatu ndi polyvinyl kolorayidi matumba apulasitiki.Matumba apulasitiki a polyvinyl chloride amafunika kuwonjezeredwa ndi zowonjezera panthawi yopanga.Zowonjezerazi ndizosavuta kusuntha mukatenthedwa kapena kukhudzana ndi zakudya zamafuta, ndikukhalabe m'zakudya ndikuwononga thupi la munthu.Choncho, musaike masamba ndi zakudya zina m'thumba lapulasitiki.Kutenthetsa mu microwave, ndipo musaike thumba la pulasitiki mufiriji.
Kuphatikiza apo, thumba la pulasitiki lopangidwa ndi zinthu zilizonse liyenera kugwiritsidwa ntchito molingana ndi kutentha komwe kumatchulidwa pakupanga kwazinthu, ndipo thumba lapulasitiki siliyenera kukhudzana ndi chakudya kwa nthawi yayitali.Mukatentha, siyani kusiyana kapena kuboola pang'ono muthumba lapulasitiki.Pofuna kupewa kuphulika, ndi kuteteza kutentha kwa madzi nthunzi kugwera pa chakudya kuchokera mu thumba la pulasitiki.
Mkaka m'thumba lathyathyathya ndi wabwino kumwa: Thumba lathyathyathya lomwe limagwiritsidwa ntchito kunyamula mkaka si filimu.Pofuna kuti mpweya ukhale wolimba, matumba apulasitiki ambiri amapangidwa ndi zigawo zingapo za filimu, ndipo wosanjikiza wamkati ndi polyethylene.Sizidzakhala vuto kumwa pambuyo pa kutentha.
Matumba apulasitiki achikuda salongedza chakudya chochokera kunja: Pakali pano, matumba ambiri apulasitiki ogwiritsidwa ntchito ndi ogulitsa ndiwo zamasamba ndi zipatso pamsika ndi owonekera pang'ono ndi oyera, komanso ofiira, akuda, ngakhale achikasu, obiriwira, ndi abuluu.Matumba apulasitiki amagwiritsidwa ntchito kunyamula zakudya zophikidwa ndi zokhwasula-khwasula kuti adye mwachindunji.Ndibwino kuti musagwiritse ntchito matumba apulasitiki achikuda.Pali zifukwa ziwiri: Choyamba, utoto womwe umagwiritsidwa ntchito podaya matumba apulasitiki umakhala ndi mphamvu yolowera komanso yosasunthika, ndipo umatuluka mosavuta ukakumana ndi mafuta ndi kutentha;ngati ndi utoto wachilengedwe, umakhalanso ndi ma hydrocarbon onunkhira.Kachiwiri, matumba apulasitiki achikuda ambiri amapangidwa ndi mapulasitiki opangidwanso.Chifukwa mapulasitiki obwezeretsedwa amakhala ndi zonyansa zambiri, opanga amawonjezera utoto kuti aphimbe.
Momwe mungadziwire kukhalapo kwa matumba apulasitiki opanda poizoni: matumba apulasitiki opanda poizoni ndi amkaka oyera, owoneka bwino, kapena opanda mtundu komanso owoneka bwino, osinthika, osalala kukhudza, ndi phula pamwamba;matumba apulasitiki a poizoni ndi amtambo kapena opepuka achikasu, Osavuta kukhudza.
Njira yoyezera madzi: Ikani thumba la pulasitiki m'madzi ndikukankhira pansi pamadzi.Chikwama chapulasitiki chosakhala ndi poizoni chimakhala ndi mphamvu yokoka yaying'ono ndipo imatha kupitilira.Chikwama chapulasitiki chapoizoni chimakhala ndi mphamvu yokoka komanso masinki akuluakulu.
Njira yodziwira gwedezani: gwirani mbali imodzi ya thumba la pulasitiki ndi dzanja lanu ndikuligwedeza mwamphamvu.Amene ali ndi mawu omveka bwino sakhala poizoni;amene ali ndi mawu osamveka ali ndi poizoni.
Njira yodziwira moto: matumba apulasitiki opanda poizoni a polyethylene amatha kuyaka, lawi lamoto ndi la buluu, pamwamba pake ndi lachikasu, ndipo amadontha ngati misozi ya kandulo pamene ikuyaka, imakhala ndi fungo la parafini, ndipo imakhala ndi utsi wochepa;matumba apulasitiki a poizoni a PVC sangapse ndi moto ndipo amasiya moto.Imazimitsidwa, lawi lamoto ndi lachikasu, pansi ndi lobiriwira, lofewa ndipo limatha kukokedwa, ndi fungo lamphamvu la hydrochloric acid.
