Panthawi yopangira zinthu zopangira zinthu, zosakaniza ziyenera kukhala zolemedwa molondola malinga ndi njira yake. Pofuna kuti mphira waiwisi waiwisi komanso wogwirizira mankhwalawo kusakanizana wina ndi mnzake, zinthu zina zimayenera kukonzedwa:

Rait rabale iyenera kuferedwa mu chipinda chowuma 60-70 ℃ musanadulidwe ndikusweka mutizidutswa tating'ono;

Block ngati zowonjezera monga parafini, stearic acid, rosin, etc. ayenera kuphwanyidwa;

Ngati mafuta ophatikizika ali ndi zosayera kapena tinthu tating'ono, zimafunikira kunenepa ndikuchotsedwa;

Zowonjezera zamadzimadzi, cormarone) zimafunikira kutenthetsa, kusungunuka, kumadzi otuluka, ndi kusefa zosanja;

Wogulitsayo amafunikira zouma, apo ayi amakonda kutchingira ndipo sangathe kuyamwa kwambiri panthawi yosakanikirana, chifukwa cha thovu panthawi yopukutirana;

3. Kudzipatula

Rait rabara ndi zotupa ndipo alibe katundu (pulasitiki) kuti akonzekere, kupangitsa kuti zikhale zovuta. Pofuna kusintha ma pulasitiki yake, ndikofunikira kukonza rabara yaiwisi; Mwanjira imeneyi, kuphatikizika kwa kuphatikizika kumabalalika mosavuta mu mphira waiwisi wosakaniza; Nthawi yomweyo, nthawi yopukutira ndi yopanga, imathandizanso kukonza zomwe zili m'Bungwe (kulowa mu nsalu ya fiber) ndi mafuta opanga. Njira yopewera mamolekyutala otalika a mphira waiwisi kuti upangidwe mawitidwe amatchedwa pulasitiki. Pali njira ziwiri zoyenga rabara waiwisi: makina oyeretsera ndi kuyeza mafuta. Makina oyendetsa magetsi ndi njira yochepetsera kuwonongeka kwa mamolekyulu otalika kwa mphira zazitali ndikuwasintha kuchokera ku boma la pulasitiki mpaka lapulitse kudzera mwa makina owonjezera kutentha. Kuyeza kwa Thermoplastic ndi njira yodziwitsa mpweya wopondaponda wothinikizidwa mu mphira wothinikizidwa mu mphira wambiri, womwe, pansi pa kutentha ndi mpweya, sufupi ndi mamolekyulu a nthawi yayitali, mwakutero kupeza mawotchi.

4. Kusakaniza

Kuti muzolowere njira zosiyanasiyana zosagwiritsira ntchito, ndikukwaniritsa magwiridwe osiyanasiyana, ndikusintha magwiridwe antchito a mphira ndikuchepetsa mtengo, ndikofunikira kuwonjezera zowonjezera zowonjezera pa mphira waiwisi. Kuphatikiza ndi njira yosakanikirana ndi pulasitiki yophika ndi mankhwala othandizira ndi kuyiyika mu simembala. Kudzera pamakina, wothandizirayo ali ndi mwayi wobalalika mu mphira waiwisi.
