Kodi pali kusiyana kotani pakati pa oponya mphira ndi polyurethane casters? Ndi iti yomwe ili yabwino kusankha

Rubber ndi polyurethane ndi zida zomwe zimagwiritsidwa ntchito m'mafakitale, ndipo zonsezi ndizomwe zimagwiritsidwa ntchito popanga ma wheel wheel. Zida zonsezi zili ndi ubwino ndi zovuta zake, ndipo gawo lotsatirali likuwunikira kusiyana kwake mwatsatanetsatane, komanso momwe mungasankhire zomwe muyenera kusankha.
Tiyeni tiyambe ndikuwona kusiyana kwakuthupi pakati pa mphira ndi polyurethane. Rubber ndi gawo lozungulira lopangidwa ndi zinthu za rabara zomwe nthawi zambiri zimakhala zosinthika komanso zosasunthika. Mphira umagawidwa kukhala mphira wachilengedwe komanso mphira wopangidwa, ndipo ukhoza kusinthidwa kuti ukhale wolimba komanso wosamva ma abrasion ngati pakufunika. Polyurethane nthawi zambiri imakhala yolimba komanso yosamva ma abrasion kuposa zoponya mphira. Ma polyurethane casters nthawi zambiri amapangidwa kuchokera ku polyurethane elastomers, omwe amakhala ndi kachulukidwe kakang'ono komanso kuuma.

Kachiwiri, oponya mphira ndi ma polyurethane casters amachita mosiyana m'malo osiyanasiyana. Zopangira mphira zimagwira ntchito bwino potengera kusinthasintha, anti-slip ndi kutchinjiriza mawu, ndipo ndizotsika mtengo komanso zosavuta kuzikonza ndi kupanga. Chifukwa chake, oponya mphira ndi chisankho chabwinoko pakafunika kusinthasintha komanso kuyamwa modzidzimutsa, monga zida zamankhwala, mipando, zida zamagetsi ndi zida zamasewera. Komano, ma polyurethane casters amachita bwino potengera kuuma, kukana abrasion, komanso kunyamula katundu, motero amakhala oyenera kwambiri m'mafakitale, kupanga, ndi zomangamanga komwe kumafunikira kulemera.
Mitundu iwiri ya casters imakhalanso yosiyana ponena za chitetezo cha chilengedwe. Zopangira mphira zimafunikira kugwiritsa ntchito mankhwala popanga, monga ma vulcanizing agents ndi ma accelerator, omwe angawononge chilengedwe. Komano, ma polyurethane casters ndi ochezeka ndi chilengedwe chifukwa ndi zinthu zomwe zimatha kubwezeredwa ndipo zimatulutsa zinyalala zochepa panthawi yopanga.

Pomaliza, pankhani ya mtengo, zopangira mphira ndizotsika mtengo pomwe zopangira pulasitiki za polyurethane ndizokwera mtengo kwambiri. Izi ndichifukwa choti zida za polyurethane ndizokwera mtengo komanso zovuta kuzikonza, kotero kuti zotayira za polyurethane ndizokwera mtengo. Zida za mphira, kumbali inayo, zimakhala zotsika mtengo ndipo njira yopangira mphira imakhala yosavuta, choncho zopangira mphira zimakhala zotsika mtengo.
Kotero, posankha magalasi a rabara ndi ma polyurethane casters, muyenera kusankha bwanji?
Ndipotu, onse ali ndi ubwino ndi zovuta zawo, ndipo kusankha kwapadera kuyenera kudalira momwe zinthu zilili. Ngati mukufuna zinthu zotanuka, zotsutsana ndi kutsetsereka komanso zowopsa, monga mipando, zida zamagetsi ndi zida zamasewera, muyenera kusankha zoponya mphira. Ngati mukufuna ma casters okhala ndi kulemera kwakukulu komanso kukana kwa abrasion, monga mafakitale, kupanga ndi zomangamanga, muyenera kusankha ma polyurethane casters.
Kupatula zopangira mphira ndi zoponya za polyurethane, palinso mitundu ina ya ma caster monga oponya nayiloni ndi ma PP. Mtundu uliwonse wa caster uli ndi ubwino ndi zovuta zake ndipo uyenera kusankhidwa malinga ndi zosowa zenizeni. Komanso, posankha casters awa, muyenera kulabadira kwambiri makulidwe a zitsulo mbale bulaketi, zitsulo mbale chuma, pamlingo waukulu, amatsimikiza kubala mphamvu ndi chitetezo cha casters, sayenera kunyalanyazidwa, yesani. kusankha mtundu wa chitsulo cha manganese wa zinthu za caster, khalidwe ndi kudalirika kwake ndipamwamba kwambiri kuposa zitsulo wamba.
Inde, ayeneranso kulabadira kukula kwa casters ndi unsembe, kuonetsetsa yosalala unsembe, kuti ntchito yake yachibadwa.
