Kodi katundu ayenera kukhala ndi zotani pa PVC ngalawa?

Ndi angati omwe ali ndi boti la galimoto yotengera inflatable padziko lonse lapansi, komanso akufuna kudziwa zomwe angachite ngati zowonongeka. Kodi mungasindikize bwanji zotsatirazi ndi zizindikiro, momwe mungachitire izo moyenera? Chabwino, palibe chomwe sichingatheke pokhapokha mutadziwa chomwe glue akuyenera kukonza pokonza bwato la PVC, komanso njira zina zomwe zingagwiritsire ntchito, popanda zomwe zingatheke kukwaniritsa zotsatira zabwino.

Malingana ndi zomwe zinachitikira "oboola ngalawa", tingathe kunena izi:

1. Poyesera kusunga ndalama, sikuyenera kugula gulu lopanda mtengo kuti akonze bwato. N'zachidziwikiratu kuti mankhwala omwe ali mu chubu sangathe kugwiritsidwa pamodzi. Komabe, gulu la mtengo wapatali kwambiri la boti la PVC ndilopanda nzeru kupeza, komwe kulipira zambiri.
2. Kukonzekera kwapamwamba ndi kotalika kwa ngalawa yotupa, Superglue kuchokera pa cyanoacrylate sizinayenera. Mothandizidwa ndi izo mukhoza kuthandizira pang'onopang'ono kanthu, koma, tsoka, kwa kanthawi.
3. Mu mawonekedwe a mitundu ina ya guluu pali zitsulo zapadera zimene zimapangitsa kukhala odekha, koma zimawononga khalidwe. Ngati zowonjezera zowonjezera mafilimu panthawi yogwira ntchito zikugwirana kwambiri ndi zala, ndibwino kuti musagwiritse ntchito chida ichi kukonzanso.
4. Chomatira cha PVC chombo chiyenera kukhala chopanda kutentha (zomwe zimaperekedwa pa chubu). Chowonadi ndi chakuti polyvinylchloride zakuthupi zimatentha kwambiri pansi pa kuwala kwa dzuwa, kotero kuti chigambachi chikhoza "kuthamanga" molakwika kuchokera mu bwato pa nthawi yovuta kwambiri. Kutentha kwake komwe gululi limagwiritsidwa ntchito pokonzanso likhoza kupirira, bwino.
5. Gulu lapadera nthawi zonse limasangalatsidwa ndi gulu lonse, chifukwa zimaganizira zofunikira za zinthu zomwe zimagwiritsidwa ntchito.
6. Malo oti agwirizane ayenera kukhala ouma kwambiri, ngakhale kutentha kwa mlengalenga kumafunikanso ngakhale kuyendetsa gluing.
7. Kuti mupeze zowonjezera zowonjezereka kwa boti la PVC pa malo osungirako amalimbikitsidwa kutentha mpaka madigiri 70, mwachitsanzo, kuyanika tsitsi kapena chitsulo chofunda. Kutentha kumawonjezera pulasitiki ya malowo ndipo kumapangitsa kuti mapulogalamuwo azigwiritsidwa ntchito bwino, komanso amapewa mipata yaying'ono mu msoko. Onani kuti mitundu ina ya guluu sizimafuna kutentha.

Ndalama zamakono zochokera kumudzi ndi zochokera kunja zimakhala zosiyana kwambiri, ndipo paipi iliyonse ndi botolo mu madigiri apamwamba kwambiri makhalidwe a mankhwalawa alipo. Komabe, ziyenera kukumbukira kuti kukonzekera bwino kwa PVC bwato ndi polyurethane, mothandizidwa ndi zomwe zingatheke kukonzanso bwino kwambiri. Mphamvu ya mgwirizano, ngati imagwiritsidwa ntchito, nthawi zina imadutsa mphamvu ya minofuyo.

Ntchito yabwino imaperekedwa ndi zigawo ziwiri zogwiritsira ntchito mabwato a PVC, makamaka omwe amamenyana akamapsa. Ndizigawozi zomwe zimagwiritsidwa ntchito popangira mabwato. Monga momwe zowonongolera ntchito zikuwonetsera, zitsulo za Desmokol, Vinikol-1520, 900I, Nthawi, Crystal, ndi Vinstick zimakhala zothandiza kwambiri.

Njira yokhala ndi njira yogwiritsira ntchito gluing: konzekerani gululi ( kusakaniza zigawo ziwirizo molingana ndi chiwerengero choyenera), kuchepetsa chigawo chogwirizanitsa ndi chigamba ndi acetone, gwiritsani ntchito ndondomeko ya guluu ndi kusunga nthawi yomwe yanenedwa m'malamulowo. Kenaka tumizani chigamba m'malo ndi mosamala, pamene mukuwotha. Chombocho chiyenera kukonzedwa popanda kupanga kupanikizika koopsa, koma musanatenge mawonekedwewo, ndipo mupite kwa masiku 1-2, kuti gululi likhale lolimba.

Ndizo nzeru zonse zoyenera kukonza kukonza zoweta za PVC.
