Chidziwitso cha malonda:
PVC-U ngalandechitoliroamagwiritsa ntchito utomoni wa polyvinyl chloride monga zopangira zazikulu, amawonjezera zowonjezera zofunika, ndipo amapangidwa ndi extrusion processing. Ndi mndandanda wa mankhwala ngalande chitoliro ndi luso okhwima ndipo chimagwiritsidwa ntchito kunyumba ndi kunja. Mankhwalawa ali ndi ubwino wa moyo wautali, kukana kwa dzimbiri, ndi zina zotero, zomwe sizingafanane ndi mapaipi achitsulo; ndi yopepuka pomanga, yosavuta kunyamula ndi kukhazikitsa, komanso yosavuta kulumikiza. Amagwiritsidwa ntchito kwambiri pomanga ngalande zachitukuko, ngalande zamadzimadzi, ndi ngalande zamadzi amvula.

Mawonekedwe:
mankhwala ali ndi ubwino wosayerekezeka moyo wautali ndi dzimbiri kukana mipope kuponyedwa chitsulo; ndi yopepuka pomanga, yosavuta kunyamula ndi kukhazikitsa, komanso yosavuta kulumikiza. Amagwiritsidwa ntchito kwambiri pomanga ngalande zachitukuko, ngalande zamadzimadzi, ndi ngalande zamadzi amvula.
1. Pamwamba kuuma ndi kumakoka mphamvu ya chitoliro zabwino, ndi chitetezo chinthuchitolirondi mkulu.
2. Mtengo wotsika, moyo wautali wautumiki, moyo wautumiki wabwinobwino ukhoza kufika zaka zopitilira 50, osafunikira kukonza ndi kukonza nthawi zonse.
3. Mapaipiwa ali ndi mphamvu yolimbana ndi dzimbiri, ma alkali, ndi mchere. Ndikoyenera kutulutsa zimbudzi zamakampani ndi zoyendera. Sichita dzimbiri kapena sikelo, kotero sipadzakhala dzimbiri ndi kuchepa mkati.
Sikophweka kutsekedwa, ndipo khoma lakunja silidzaipitsidwa chifukwa cha dzimbiri.payipi, kuonetsetsa kukongola kwa nyumbayo.
4. Chiwombankhanga cha chitoliro ndi chaching'ono, madzi oyenda ndi osalala, osavuta kutsekedwa, ndipo ntchito yokonza ndi yochepa.
5. Zomwe zili ndi mpweya wambiri wa oxygen ndipo zimazimitsa zokha.
6. Kukula kwa mzere wowonjezera wa payipi ndi kakang'ono, ndipo kuchuluka kwa kusinthika komwe kumakhudzidwa ndi kutentha kumakhala kochepa. Thermal conductivity ndi zotanuka modulus ndi yaying'ono, ndipo anti-kuzizira ntchito bwino kuposa zitsulo zotayira kukhetsa mapaipi.
7. Mipope ndi zokometsera zimagwirizanitsidwa ndi guluu, njira yomanga ndi yophweka, ntchitoyo ndi yabwino, ndipo ntchito yoyikapo ntchito ndipamwamba.
8. Ndiwopanda poizoni, ulibe mchere wamchere wapoizoni ndi mankhwala ena oopsa, ndipo ulibe vuto lililonse m’thupi la munthu.
