Pulasitiki ya PP ndi polypropylene, dzina la Chingerezi: Polypropylene.Kachulukidwe kake ndi kakang'ono, ndipo mphamvu yake, kuuma, kuuma ndi kukana kutentha ndi zabwino.PVC ndi polyvinyl kolorayidi (Polyvinyl kolorayidi Chidule cha polima), dzimbiri resistance.PC ndi chidule cha Polycarbonate, amene ali kukana zimakhudza, kukana matenthedwe kupotoza, kukana zabwino nyengo ndi mkulu hardness.ABS ndi pulasitiki zomangamanga, dzina lonse ndi “acrylonitrile -butadiene-styrene copolymer”, Chingerezi ndi Acrylonitrile
butadiene Styrene copolymers.Ili ndi mphamvu zambiri, kulimba kwabwino komanso kukonza kosavuta.Zigawo zitatu ndi zipangizo ndizosiyana.Atatu ndi polymerization yaing'ono maselo organic zipangizo mu macromolecular zipangizo, ndi zikuchokera pamaso polymerization ndi osiyana, chifukwa mu kusiyana zikuchokera, mawotchi mphamvu, kutentha kukana, etc. pambuyo polymerization.
Zotsatirazi ndi zabwino ndi kuipa kwamilandu ingapo yamatrolley:
Mlandu wa trolley wa ABS ndi chinthu chatsopano, komanso ndi mafashoni otchuka posachedwa.Chinthu chachikulu ndi chakuti ndi chopepuka kuposa zipangizo zina, pamwamba pake chimakhala chosinthika komanso chokhazikika, ndipo kukana kukhudzidwa ndi bwino kuteteza zinthu zamkati.Simamva mphamvu ngati ili yofewa, koma kwenikweni imasinthasintha kwambiri.Munthu wamkulu wamba alibe vuto kuima pa izo.Ndi yabwino kuyeretsa.Choyipa chake ndi chakuti sachedwa kukala.
Nsalu ya Oxford Iyi ndi mtundu wa nayiloni.Ubwino wake ndikuti ndi wosavala komanso wothandiza.Choyipa chake ndikuti ndizofanana.Zimakhala zovuta kusiyanitsa katundu pabwalo la ndege, ndipo ndizolemera, koma palibe chifukwa chodera nkhawa za kuwonongeka kwa bokosilo.Momwemonso, ndi kuwonjezeka kwa abs pakapita nthawi, kuvala pamwamba kungawonekere kwa nthawi yaitali pambuyo pogwiritsira ntchito pang'ono.
Chovala cha pu boarding trolley ndi chopangidwa ndi chikopa cha pu.Ubwino wamtunduwu ndikuti ndi wofanana kwambiri ndi zikopa za ng'ombe, zikuwoneka zapamwamba, ndipo siziwopa madzi ngati chikopa chachikopa.Choyipa chake ndikuti sichimavala komanso chosalimba kwambiri, koma mtengo wake ndi wotsika..
canvas Mabokosi amtundu woterewu sakhala ofala kwambiri, koma kwa chinsalu, mwayi waukulu ndikuti ndi wosavala ngati nsalu ya Oxford, pomwe choyipa ndichakuti kukana kwake sikuli bwino ngati nsalu ya Oxford.Mtundu wa zinthu za canvas ndi wofanana kwambiri, ndipo malo ena amatha kukhala owala.Zowoneka bwino.M'kupita kwa nthawi, pali malingaliro akale ndi apadera a vicissitudes.
Mlandu wa pvc trolley umadziwikanso kuti hard case.Amawoneka ngati munthu wolimba.Ndiwotsutsana ndi dontho, madzi, osagwira ntchito, osavala komanso apamwamba.Tinganene kuti ndi wamphamvu kwambiri kuposa abs.Adzadandaula za zokala chifukwa chogwira movutikira.Chifukwa sizidzakhala zoonekeratu.Choyipa chachikulu ndikuti ndi cholemetsa, chomwe chimakhala pafupifupi ma kilogalamu 20 nthawi iliyonse.Muyenera kudziwa kuti ndege zambiri zimaletsa ma kilogalamu 20, zomwe zikutanthauza kuti kulemera kwa bokosi kumakhala theka.
chikopa cha ng'ombe
Nthawi zambiri, chikopa cha ng'ombe ndichokwera mtengo kwambiri.Ndiwokwera mtengo kwambiri malinga ndi chiwerengero cha mtengo / ntchito.Imaopa madzi, kuyabwa, kupanikizika, ndi kukanda.Komabe, malinga ngati asungidwa bwino, bokosilo ndilofunika kwambiri.Sizokonda zachilengedwe kugwiritsa ntchito zikopa.Kumbukirani kuti palibe vuto ngati palibe kugulitsa.
