Madontho aChitoliro cha PEZolumikizira nthawi zambiri zimachitika chifukwa cha mphamvu yochepa pa chinthucho, kusadzaza zinthu mokwanira, komanso kapangidwe kosayenera ka chinthucho. Mabowo nthawi zambiri amawoneka m'mbali yokhuthala yomwe ili yofanana ndi khoma lopyapyala. Mabowo a mpweya amayamba chifukwa cha pulasitiki yosakwanira m'bowo la nkhungu, pulasitiki yakunja yozungulira imazizira ndi kuuma, ndipo pulasitiki yamkati imachepa kuti ipange vacuum. Zambiri mwa izi zimachitika chifukwa cha zinthu zosauma bwino, komanso ma monomers otsala ndi zinthu zina zomwe zili m'zinthuzo.
Kuti muweruze chomwe chayambitsa ma pores, ndikofunikira kungoyang'ana ngati thovu la zida za PE pipe fittings limawonekera nthawi yomweyo pamene nkhungu yatsegulidwa kapena pambuyo pozizira. Ngati zimachitika nthawi yomweyo pamene nkhungu yatsegulidwa, nthawi zambiri ndi vuto la zinthu, ngati zimachitika pambuyo pozizira, ndi vuto la nkhungu kapena jekeseni.

(1) Vuto la zinthu:

①Zinthu zouma ②Onjezani mafuta ③Chepetsani zinthu zosasunthika zomwe zili muzinthuzo

(2) Mikhalidwe yopangira jakisoni

①Kuchuluka kwa jakisoni kosakwanira; ②Onjezani kuthamanga kwa jakisoni; ③Onjezani nthawi yojambulira; ④Onjezani nthawi yonse yokakamiza; ⑤Onjezani liwiro la jakisoni; ⑥Onjezani nthawi yojambulira; ⑦Nthawi yojambulira si yachilendo chifukwa cha zifukwa zogwirira ntchito.

(3) Vuto la kutentha

①Zinthu zotentha kwambiri zimayambitsa kuchepa kwakukulu; ②Zinthu zozizira kwambiri zimapangitsa kuti zinthuzo zisadzaze bwino komanso kuti zisadzaze bwino; ③Kutentha kwambiri kwa nkhungu kumapangitsa kuti zinthu zomwe zili pakhoma la nkhungu zisaume msanga; ④Kutentha kochepa kwa nkhungu kumapangitsa kuti nkhungu isadzaze bwino; ⑤Nkhunguyo ili ndi malo otentha kwambiri ⑥Sinthani dongosolo loziziritsira.

(4) Vuto la nkhungu;

①Onjezani chipata; ②Onjezani wothamanga; ③Onjezani njira yayikulu; ④Onjezani dzenje la nozzle; ⑤Konzani utsi wa nkhungu; ⑥Linganizani kuchuluka kwa kudzaza nkhungu; ⑦Pewani kusokoneza kayendedwe ka kudzaza nkhungu; ⑧Kakonzedwe ka chakudya cha chipata M'gawo lokhuthala la chinthucho; ⑨Ngati n'kotheka, chepetsani kusiyana kwa makulidwe a khoma la zida za PE; ⑩Kuzungulira kwa jakisoni komwe kumachitika chifukwa cha nkhungu sikwachilendo.

(5) Mavuto a zida:

①Onjezani mphamvu ya pulasitiki ya makina osindikizira jekeseni; ② Pangani nthawi yojambulira jekeseni kukhala yabwinobwino;

(6) Vuto la kuzizira:

①TheZolumikizira mapaipi a PEZimaziziritsidwa kwa nthawi yayitali mu nkhungu kuti zisachepe kuchokera kunja kupita mkati ndikufupikitsa nthawi yozizira ya nkhungu; ②Zolumikizira za PE zimaziziritsidwa m'madzi otentha.
