Kutheni i-Pom-H kunye ne-POM-C

Iplastiki ngokweenkcukacha

I-Acetal = Polyooxyylene

Iipropathi eziphambili: Amandla oMatshini abaPhezulu kunye noThando, ukuSebenzisa okuPhakamileyo, ukuHanjiswa okuhle, ukuSebenza kweNdalo, uHubrication, ukuxhaswa kwemichiza.

Imbali yentsimbi yohlanga: i-herman yafumanisa intsimbi ngo-1920, i-DUPENT ivelise i-duporch ivelise i-Pom ye-Acetal Pom-H ngo-1956, kwaye uCelanese wancanca i-PolyformalEyeymer POMORYEHHHYRE COMOLTEREREmer POMORYEHYRERGEREmer POMORNALMERERGEREREREREmer POMORNARMERERGERGERGEREREmer POMORFEYMEYMEYSREREREREREREREREmer

I-Acetal yi-Acetal, ekwabizwa ngokuba yiPolyacetal, yaziwa ngamachwekhanyisi njenge-polyfoldEhhyde, okt Polyoxythylene (POM), yi-foom ye-clealdehydege

Amaxesha amaninzi, i-acetal icinyiwe kwi-PM ekwintetho.

Isakhiwo sekhemikhali se-POM

I-Acetal ihlala yaziwa njengensimbi yomdyarho kwaye ihlala ifumaneka ngobumnyama nabamhlophe, i-acetal-emnyama kunye ne-acetal-emhlophe.

I-Acetal iqhubekisiwe kwimilo emise ye-billetlet kwaye ikhutshiwe emakhishini, iintonga kunye neetyhubhu.

I-Acetal inamandla amakhulu omatshini kunye nokuqina, iimpawu ezintle zokutsala (ukulingana okuphantsi kokuxinana), kwaye ukuchitha kakubi.

Kuba i-acetal ifumana amanzi amancinci, inozinzo oluhle kakhulu kwaye lukhetho oluhle lwemilo entsonkothileyo kunye neenxalenye ezilinganayo. Kananjalo ngenxa yokungena kwamanzi asezantsi, iibhetri zabarhwebi ngaphandle kwe-nylon yinto ye-4 kumswakazi ophezulu okanye iinkqubo eziphantsi.

Ngenxa yesakhiwo sekhemikhali se-radimic yentsimbi, ayizinzanga kwiimeko ze-acidic kunye namaqondo obushushu aphezulu, apho i-polymer ithoba. Ngenxa yoko, i-POM ihlala ichithwe kunye ne-cyclic eths enje nge-ithoylene oxide okanye i-dispide ukutshintsha isakhiwo semichiza kwaye siphucule uzinzo.

Iindidi ezahlukeneyo zepropathi yomadyarho: ezingaphelelwanga, eziguqulweyo, eziguqulweyo eziphantsi, iindidi ezizalisekileyo, kunye nezinye. I-cycloidal ye-cycloidal iqiniswe kunye neentsinga zeglasi, i-carbon fibers okanye amabala eglasi kumandla aphezulu okanye ukuqina. Ukudibanisa i-cyclosteel ngerabha, i-TPU kunye nezinye iipolymers zibangela ukuhlanganisa amandla aphezulu empembelelo. Ukongeza igraphite, i-Ptfe, iifilimu zeminerali, njl. Ukuphucula ukugula kunye nokuthambisa.

Ukongeza, ngenxa yexabiso elikhulu leoksijini kwimolekyuli, kunzima ukuyidlulisela i-qabenga kwaye inomgangatho wobushushu obuqhubekayo omalunga ne-40 ° C ukuya kwi-120 ° C.

Umzekelo Iinxalenye zombane eziqhotyoshelweyo. Izinto zokunxibelelana namanzi, ukuqhekeza okunganyangekiyo ezixhaphakileyo eziphezulu. Izinto ezahlukeneyo zokutya, ezenza amayeza nokusela amashishini amanzi, kunye netekhnoloji yezonyango.

I-POM-H, i-POM-c

Zimbini izinto ezahlukeneyo ze-POM, i-acetal homopolymer i-Pom-H kunye ne-Acetal Com-C. Zineepropathi zempembelelo ezifanayo.

I-POM-H = i-acetal homollymer, i-POM-C = i-acetal copolymer.

I-Acetal Homopolymer Pom-H kunye ne-Acetal Com-C Drties

I-POM-H iveliswa yindlela ye-anion ye-anioldehydehyde, ebika kakuhle, ikhokelela ekukhuleni okuphezulu namandla; I-POM-h yi-10-15% eyomeleleyo kune-POM-C.

Nangona kunjalo, i-POM-C inomchasi ophakanyisiweyo kunye nokunyibilika okuphezulu kune-POM-H. Kwakhona, ineenkqubo eziphezulu xa kuthelekiswa ne-POM-H. Ngenxa yoko, i-POM-C ibe lolona hlobo lusetyenzisiweyo lwe-POM, i-accounting ngama-75% ethengiswa yi-POM.

I-POM-H ilungele ukusetyenziswa kwezicelo ezifuna ukumelana ne-abrasion elungileyo kunye nokulingana okuphantsi kokuxabana, kwaye i-PM-C ithathwe kakuhle kwizicelo ezifuna ukulingana.

Ukushwankathela, i-POM-H kunye ne-POM-C ibe ngumahluko olandelayo.

FAQ:

Yintoni umahluko phakathi kwe-POM kunye ne-POM-C?

I-POM VS. POM-C: Ukuqonda umahluko kubuNjineli ...

I-PM-C, ikwabhekiswa kuye njenge-Acetal Copolymer, iveliswa kusetyenziswa inkqubo yokugcwala. Ngokwazisa nge-coononomer ngexesha le-polymerization, izinto ezibonakalayo zibonisa ubugqwetha ophuculo, ukuxhathisa kwempembelelo, kunye nokuxhathisa okungcono kwemichiza xa kuthelekiswa ne-Pom.

Nguwuphi umahluko phakathi kwe-Pom Copolymer kunye ne-homollymer?

Polyacetal (POM) | Ukukhetha i-homopolymer okanye i-copolymer?

Ngenxa ye-crystallies ephezulu, i-homollymer ineqondo lokushisa eliphezulu lobushushu kodwa amabakala e-Copolymer asebenzise amaqondo obushushu aqhubekayo ngenxa yozinzo lwexesha elide.

Nguwuphi umahluko phakathi kwe-acetal ne-PM-C?

Xa kuthelekiswa ne-Acetal Homopolymer, i-PM-C ibonelela ngokuxhathisa kwiikhemikhali kwaye isebenzise i-fictions, kodwa ingaphantsi kwe-PM-H kwaye ayisiyonto inzima yokunxiba. I-Acetal Copolymer ikwanayo neqondo lobushushu eliphantsi kunye nokunyibilika kune-acetal homollymer.

Yintoni umahluko phakathi kwe-delrin kunye ne-POM C?

UDelrin unobunzima obungama-86 unxweme d ngelixa i-pom copolymeds inobunzima obungama-85 unxweme D. Ke, uDelrin uya kuba unganyangeki kwiimpembelelo kunye ne-abrasion. Kwakhona, iya kuba ne-coandetion ephantsi. Ke ngoko, iya kuba nakho ukutywina kwezinye iindawo ngokulula.

Yeyiphi iplastiki eyomeleleyo kunoDelrin?

I-Delrin vs nylon: ukuthelekisa ezimbini zeplasitiki zeplastiki ...

Ngelixa zombini izixhobo zomelele kwaye ziqinile, i-NYLOLO inamandla aphezulu e-thensile ye-12,000 psi kune-debrin ene-10,000 ye-PSI. Nangona kunjalo, zombini ezi zinto zihambahamba ngaphakathi kwaye zinefuthe eliphezulu kwaye zinxibe ukunganyangeki.

Zeziphi izinto ezingcono kune-delrin?

I-NYLOL yeyona nto ilungileyo yokusebenza nayo ukuba ujonge ukusebenzisa amandla okuprinta i-3D, kwaye nayo inokusetyenziswa kwiimeko zobushushu eziphezulu kune-derrin.
