PC ndi mtundu wa pulasitiki waukadaulo wokhala ndi magwiridwe antchito abwino kwambiri mbali zonse. Ili ndi ubwino waukulu pakukana kugwedezeka, kukana kutentha, kukhazikika kwa mawonekedwe ndi kuchedwa kwa moto. Chifukwa chake, imagwiritsidwa ntchito kwambiri mu zida zamagetsi, magalimoto, zida zamasewera ndi zina. Komabe, maunyolo a mamolekyulu a PC ali ndi mphete zambiri za benzene, zomwe zimapangitsa kuti maunyolo a mamolekyulu azisuntha, zomwe zimapangitsa kuti PC isungunuke kwambiri. Panthawi yokonza, maunyolo a mamolekyulu a PC amalunjika. Pambuyo pokonza, maunyolo ena a mamolekyulu omwe sanasinthe kwathunthu mu chinthucho amayamba kubwerera ku mawonekedwe awo achilengedwe, zomwe zimapangitsa kuti pakhale kupsinjika kwakukulu muzinthu zopangidwa ndi PC zomwe zimapangidwa ndi jakisoni, zomwe zimapangitsa kuti pakhale ming'alu panthawi yogwiritsa ntchito kapena kusungira; nthawi yomweyo, PC ndi chinthu chomwe sichimakhudzidwa ndi notch. Zofooka izi zimalepheretsa kukula kwaMapulogalamu a pakompyuta.

Pofuna kupititsa patsogolo kusinthasintha kwa mphamvu ya PC komanso kupsinjika kwa mphamvu yake, zinthu zolimbitsa thupi nthawi zambiri zimagwiritsidwa ntchito polimbitsa PC. Pakadali pano, zinthu zina zomwe zimagwiritsidwa ntchito kwambiri posintha zinthu zolimbitsa thupi zomwe zili pamsika ndi monga zinthu zolimbitsa thupi za acrylate (ACR), zinthu zolimbitsa thupi za methyl methacrylate-butadiene-styrene (MBS) ndi zinthu zolimbitsa thupi zopangidwa ndi methyl methacrylate ngati chipolopolo, acrylate ndi silicone ngati maziko. Zinthu zolimbitsa thupizi zimagwirizana bwino ndi PC, kotero zinthu zolimbitsa thupi zimatha kugawidwa mofanana mu PC.

Pepalali linasankha mitundu 5 yosiyanasiyana ya zinthu zolimbitsa thupi (M-722, M-732, M-577, MR-502 ndi S2001), ndipo linayang'ana zotsatira za zinthu zolimbitsa thupi pa zinthu zokalamba za PC thermal oxidation, zinthu zokalamba za 70 ℃ zotentha, ndi zinthu zokalamba za kutentha konyowa (85 ℃/85%) kudzera mu kusintha kwa kuchuluka kwa madzi osungunuka, kutentha kwa kutentha ndi zinthu zamakina.

Zipangizo zazikulu:

UP-6195: mayeso oletsa kutentha konyowa (kunyowa kutentha kwambiri komanso kotsikachipinda choyesera kutentha);

UP-6196: mayeso osungira kutentha kwambiri (uvuni wolondola);

UP-6118: mayeso a kutentha (kuzizira ndi kutentha)chipinda choyesera);

UP-6195F: Kuzungulira kwa kutentha kwapamwamba ndi kotsika kwa TC (chipinda choyesera kusintha kwa kutentha mwachangu);

UP-6195C: mayeso a kugwedezeka kwa kutentha ndi chinyezi (zipinda zitatu zoyesera zonse);

UP-6110: mayeso othamanga kwambiri (kuthamanga kwambiri)chipinda choyesera kukalamba);

UP-6200: mayeso okalamba a UV (chipinda choyesera kukalamba cha ultraviolet);

UP-6197: mayeso a dzimbiri a kupopera mchere (chipinda choyesera kupopera mchere).

Mayeso a magwiridwe antchito ndi mawonekedwe a kapangidwe kake:

● Yesani kuchuluka kwa madzi osungunuka a zinthuzo malinga ndi muyezo wa ISO 1133, momwe mayesowo alili ndi 300 ℃/1.2 kg;

● Yesani mphamvu yokoka ndi kutalika kwa zinthuzo zikasweka malinga ndi muyezo wa ISO 527-1, mlingo woyeserera ndi 50 mm/mphindi;

● Yesani mphamvu ya kusinthasintha ndi modulus ya zinthuzo motsatira muyezo wa ISO 178, mlingo wa mayeso ndi 2 mm/mphindi;

● Yesani mphamvu ya kugwedezeka kwa zinthuzo malinga ndi muyezo wa ISO180, gwiritsani ntchito makina opangira zitsanzo za kugwedezeka kuti mukonze kugwedezeka kofanana ndi "V", kuzama kwa kugwedezeka ndi 2 mm, ndipo chitsanzocho chimasungidwa pa -30 ℃ kwa maola 4 mayeso a kugwedezeka kwa kutentha kochepa asanachitike;

● Yesani kutentha kwa zinthuzo malinga ndi muyezo wa ISO 75-1, kutentha kwake ndi 120 ℃/min;

●Mayeso a Yellowness index (IYI):Kutalika kwa mbali yopangira jakisoni ndi kokulirapo kuposa 2 cm, makulidwe ndi 2 mm. Mbale yamitundu yozungulira imayesedwa kukalamba kwa okosijeni wotentha, ndipo mtundu wa mbale yamitundu isanayambe komanso itatha kukalamba umayesedwa ndi spectrophotometer. Chidacho chiyenera kuyesedwa musanayese. Mbale iliyonse yamitundu imayesedwa katatu ndipo chizindikiro chachikasu cha mbale yamitundu chimalembedwa;

●Kusanthula kwa SEM:Chingwe chopangidwa ndi jakisoni chimadulidwa, golide amathiridwa pamwamba pake, ndipo mawonekedwe ake pamwamba amawonedwa pansi pa mphamvu inayake yamagetsi.
