Zima kuti, ife tonse tikudziwa kuti chinthu ichi kwa pulasitiki pambuyo yozizira adzakhala kwambiri Chimaona, chifukwa chiyani?

Pulasitiki ndi chigawo chachikulu cha macromolecular aggregates, macromolecules yodziwika ndi kutentha otsika pamene kuyenda pang'onopang'ono, kutentha, kudya kuyenda.M'nyengo yozizira, kayendedwe ka maselo ndi pang'onopang'ono, pamene pulasitiki ndi mphamvu yakunja, chinthu mapindikidwe, chifukwa cha kayendedwe ka maselo ndi pang'onopang'ono, mphamvu ya kunja si kosavuta kutha (kufanana mkati kupsinjika maganizo) kapena kudyedwa (maselo unyolo kukangana), kotero sachedwa kupsinjika ndende, Pamene maganizo mkati kumlingo wakuti, ndi macromolecules pa wosweka, kuyambitsa ming'alu, ming'alu adzakhala anatchula maganizo ndende ndi kufalitsa pulasitiki pa wosweka.

Njira: Nthawi zambiri, chinyezi chochepa chomwe chimalowetsedwa m'thumba chikhoza kuchepetsa kupasuka.

Amagwiritsidwa ntchito kwambiri m'mafakitole amagetsi, ma motors, kuyatsa, zingwe zamakompyuta, zoseweretsa zamagetsi ndi zinthu zina, kukonza zingwe zamasitima, kukonza mapaipi amafuta pazida zamakina, kuyika njinga kapena kumanga zinthu zina.Mapangidwe olimba a thupi, moyo wautali wautumiki.7 inchi.Kukana bwino kwa dzimbiri, kutchinjiriza kwabwino, kosavuta kukalamba, komanso kupirira kwamphamvu.Mutu wozungulira, wochepa umachotsa zopinga ndikupangitsa kuti zikhale zosavuta kudutsa magawano popanda m'mphepete lakuthwa.

Ubwino wake ndi:

1. Wokhuthala lamba, unakhuthala mkati kusanthula malo, yunifolomu ndi zolimba, amphamvu kuluma mphamvu.

2. Kulimba kwa tayi, tayi yocheperako, komanso mawonekedwe osiyanitsidwa ndi anthu amalepheretsa zinthu kugwa.

3. Kumapeto kwa tayi ya chingwe kumakhala ndi anti-skid-tooth-tooth, zomwe zimakhala zosavuta kuziyika ndikuzinyamula.

4. Pamwamba pa tayi ya chingwe ndi loko ndi yosalala, popanda ma burrs oonekera, ndipo sikophweka kukanda khungu.

5. Tayi ya chingwe imapanikizidwa ndi ukadaulo wapamwamba, zidazo zimamveka bwino, kulimba kwake kumakhala kolimba, sikophweka kumasula mukakakamira, kosavuta kutsetsereka, kosavuta kuthyoka.
