What is the purpose of using POM ?

Yintoni injongo yokusebenzisa i-POM?

I-Page Object Model (POM) yipatheni yoyilo esetyenziswa kakhulu kwi-automation yovavanyo ukuphucula ukugcinwa, ukwandiswa, kunye nokusetyenziswa kwakhona kwezikripthi zovavanyo oluzenzekelayo. Ikhuthaza indlela ecwangcisiweyo yokuhlela ikhowudi kwaye yenza kube lula ukulawula nokuhlaziya iimeko zovavanyo njengoko usetyenziso lutshintsha.

Isetyenziselwa ntoni i-POM?

I-Polyoxymethylene (POM), ekwaziwa ngokuba yi-acetal okanye i-polyacetal, yi-thermoplastic yobunjineli eneempawu ezibalaseleyo. I-POM isetyenziswa rhoqo ekuveliseni iindawo ezichanekileyo ezifuna ukuqina okuphezulu, ukungqubana okuphantsi, kunye nozinzo olulinganayo.

Iintonga zePolyacetal / POM-C. Izinto zePOM, ezibizwa ngokuba yi-acetal (ezaziwa ngokuba yiPolyoxymethylene ngokwekhemikhali) zine-copolymer ebizwa ngokuba yiPOM-C Polyacetal plastic. Zinobushushu obusebenzayo obuhlala buhleli obuqala kwi -40 ° C ukuya kwi +100 ° C.

I-POM yiplastiki eqinileyo neqinileyo, enamandla alingana nalawo eplastiki, ngoko ke ikhuphisana umz. nee-epoxy resins kunye neepolycarbonates.

Apha ngezantsi malunga ne-MC nylon rod, intshayelelo yetyhubhu ye-nylon:

Intonga ye-MC nylon ephosiweyo ifumaneka ngobukhulu obahlukeneyo kunye neemilo, nto leyo eyenza ukuba ibe nokuguquguquka kwiimfuno ezahlukeneyo zobunjineli. Ubuchule bayo bokwenza izinto buvumela ukwenziwa kunye nokwenza ngokwezifiso kube lula, nto leyo eyenza ukuba ibe lukhetho oluthandwayo kubavelisi abafuna izinto ezingabizi kakhulu nezihlala ixesha elide kwiimveliso zabo. Izinto zingacutshungulwa, zigqojwe, kwaye zicofwe ngokulula ukuze zihlangabezane neemfuno ezithile zoyilo, nto leyo enika ukuguquguquka kwiinkqubo zemveliso.

Ukongeza kwiimpawu zayo zoomatshini, intonga ye-MC nylon ephosiweyo ikwabonisa ukumelana okuhle kweekhemikhali, nto leyo eyenza ukuba ifaneleke ukusetyenziswa kwiindawo apho ukuchatshazelwa ziioyile, izinyibilikisi, kunye neekhemikhali kuyingxaki. Oku kwenza ukuba ibe yinto ekhethwayo yokusetyenziswa kwimizi-mveliso yokucubungula iikhemikhali, ukucubungula ukutya, kunye neemoto.

Lilonke, intonga ye-MC nylon ephosiweyo inika indibaniselwano yokusebenza okuphezulu, ukuqina, kunye nokuguquguquka, okwenza ukuba ibe lukhetho olukhethwayo kwiintlobo ngeentlobo zezicelo zoshishino. Amandla ayo okumelana nemithwalo enzima, ukumelana nokuguguleka kunye nokukrweleka, kunye nokusebenza ngokuthembekileyo kwiimeko ezinzima kuyenza ibe yinto exabisekileyo kwiinjineli kunye nabavelisi abafuna izinto zeplastiki ezikumgangatho ophezulu. Ngenxa yeempawu zayo ezintle kunye nokulula kokwenziwa, intonga ye-MC nylon ephosiweyo iyaqhubeka nokuba lukhetho oludumileyo kumacandelo obunjineli kunye nemveliso.
