Ndi jekete iti ya chingwe yomwe ili yoyenera kugwiritsa ntchito? PUR, TPE kapena PVC?

Pali mitundu yosiyanasiyana ya majekete a chingwe ndipo jekete lililonse limagwira ntchito bwino pa ntchito yakeyake. Majekete atatu akuluakulu a chingwe cha sensor ndi PVC (Polyvinyl Chloride), PUR (polyurethane) ndi TPE (thermoplastic elastomer). Mtundu uliwonse wa jekete uli ndi maubwino osiyanasiyana monga kugwiritsa ntchito madzi onyowa, osapsa kapena opindika kwambiri. Kupeza mtundu woyenera wa jekete lanu kungakulitse moyo wa chingwecho.

PVCndi chingwe chogwiritsidwa ntchito nthawi zambiri ndipo chimapezeka paliponse. Ndi chingwe chogwiritsidwa ntchito nthawi zambiri, ndipo nthawi zambiri chimakhala ndi mtengo wabwino kwambiri. PVC imakhala yolimba kwambiri chifukwa cha chinyezi, zomwe zimapangitsa kuti ikhale chisankho chabwino chogwiritsidwa ntchito potsuka.

PURimapezeka kwambiri ku Asia ndi ku Ulaya. Mtundu wa jekete la chingwe uwu uli ndi mphamvu yolimbana ndi kusweka, mafuta ndi ozoni. PUR imadziwika kuti ilibe Halogen, ilibe: chlorine, ayodini, fluorine, bromine kapena astatine. Mtundu wa jekete uwu uli ndi kutentha kochepa poyerekeza ndi mitundu ina ya jekete, -40…80⁰C.

TPEChingwechi chimasinthasintha, chimatha kubwezeretsedwanso ndipo chili ndi kutentha kozizira kwambiri, -50…125⁰C. Chingwechi chimapirira kukalamba chifukwa cha kuwala kwa dzuwa, UV ndi ozone. TPE ili ndi mphamvu yosinthasintha kwambiri, nthawi zambiri imakhala 10 miliyoni.

Gome ili m'munsimu likufotokoza za kukana kwa zinthu zosiyanasiyana. Dziwani kuti ziwerengerozi zimadalira magwiridwe antchito apakati. Kuphatikiza kosankhidwa mwapadera kwa jekete kungathandize kuti magwiridwe antchito ayende bwino.
