I-POM POLUCOALT, ngamanye amaxesha siyibiza ngokuba yi "Sai Steel", ngamanye amaxesha siyibiza ngokuba "yingxowa", kutheni le nto igama elinjalo? Kuba, igama lihlala lihleli ngabazali bayo, oko kukuthi, umvelisi wayo.
Siyazi ukuba zimbini iintlobo eziphambili zeparaformalEldehyde, enye ibizwa ngokuba yi-copolyformalmehyde, kwaye enye ibizwa ngokuba yi-homopolyformalmehyde. Ukuyilwa kwe-copolymerization yenkampani yaseFomaldehyde (i-United States Celane) ibhaliswe igama elingathethekiyo, elibizwa ngokuba yi "Celcon", iguqulwe ngentambo ", kunye nokuguqulwa kwe-homopolylize yenkampani (i-United States ikwazile i Igama lophawu, igama elithi "Delrin", ngokuguqulelwa ngentliziyo njenge 'Delrin'. I-paramifolde ingumgca we-polymer engenamakhonkco, uxinzelelo oluphezulu kunye ne-crystallies ephezulu. Ngokweziseko ezahlukeneyo zekhemikhali kwi-molecular thein, inokwahlulwa ibe ziintlobo ezimbini ze-homo- kunye ne-co-polyfolthelehbolede.
Umahluko obalulekileyo phakathi kwezi zinto zimbini zezi: i-homopolymer ye-fomoldehydehyde yoxinano, indawo yokunyibilika iphantsi, i-alkali iphantsi, i-Alkali iphantsi kakhulu, i-United States ithathe i-homopolylize ye-gomooldehyde . Kunye neCartlyformaldeXolDehbooldde Derity, I-Crystallinity, indawo yokunyibilika, amandla aphantsi, ungazinzi, uzinzo lweqondo lobushushu lubanzi, ukulungisa i-acid kwaye i-alkali ingcono. Iplastiki yenjineli enesixhobo esihle kakhulu. Inezinto ezilungileyo zomzimba, zoomatshini kunye neekhemikhali, ngakumbi ukumelana nokuchasana.
Ihlala yaziwa njengensimbi yomdyarho, kuba bekukho iplasitiki yesithathu. Ilungele ukuveliswa kweenxalenye zenxalenye, iinxalenye zothumelo, kunye neshishini lekhemikhali, izixhobo kunye namanye amalungu. I-United States Celanese yaqala ukugcwala kwe-formaldehydehyde.
Iimpawu zobunjineli zePlastiki:
I-1, i-POM inokusetyenziswa ngaphandle komoyike ngaphambi kokuba isebenze, kungcono ukubakho ngexesha lokuqhutywa (malunga ne-80 ℃), uzinzo lwemveliso yemveliso ilungile;
I-2, i-Pom yokulungisa i-POM inqabile, emgqomeni ihlala ixesha elide okanye iqondo lobushushu lingaphezulu kwe-220 ℃ iya kubola, ivelise irhasi ecaphukisayo;
I-3, i-POM yenaliti yenzuzo yokubumba iba nkulu (ifana noxinzelelo lwenaliti), ukuze kuncitshiswe uxinzelelo lwehla, isantya sescrew asinakuba nkulu kakhulu, i-stol steyili yexabiso elingaphantsi.
4, Iimveliso ze-POM zinenqanaba elikhulu eliphantsi, kulula ukuvelisa i-shrinkage okanye i-SPRFOMORK, i-POM ishushu (i-POM ye-POM ishushu (80 ~), imveliso ishushu kakhulu xa inyanzelekile.
I-5, i-POM ifanele ibe kwi "Preimucine, isantya esiphakathi, iqondo lobushushu eliphantsi, ubushushu obuphezulu obungaphantsi" phantsi kweemeko zokubumba, iimveliso ezichanekileyo kufuneka zilawule amaqondo obushushu xa ubumba;
6, ngamandla omatshini obuphezulu kunye nobungqola;
7, amandla okutyeba okuphezulu;
Ukuxhathisa kwendalo esingqongileyo, ukunganyangeki okuhle kwizihlalo zendalo;
9, Ukungaxhathisi okuqatha kwimpembelelo ephindaphindiweyo, iipropathi ezilungileyo zombane, ukubuyela kwimeko yesiqhelo, ngokuzithandela, ukunyangwa okuhle, uzinzo oluhle kakhulu.
Usetyenziso oluqhelekileyo lwePlasikini ye-POM: inokuthatha indawo uninzi lweentsimbi ezingenantlonelo, iimoto, izixhobo ze-piring, i-boings, i-piking, i-piings, i-gomps, i-pumps, idraini, kunjalo kwi. I-POM yePlasitiki yePlasitiki: IParaformalEhyde yindawo egudileyo, i-glossy hard kunye nezinto ezimnyama, ezimhlophe, ezinamanzi anqabileyo. Iimpawu zokudibanisa ukulula ukutshisa, kude nomlilo uqhubeka nokutsha, idangatye lityheli kwisiphelo esiphezulu, isiphelo esisezantsi se-roll, sisemva kwe-formaldehyehyehyehyehyehyehyehyehyehyehyehboles ecaphukisayo, ivumba lentlanzi. I-POM ye-opaque, imibala elungileyo, amandla athile e-1.41-1.43 g / cm3, iqondo lokuhlwayela i-170-200 ℃, iimeko ezomisa iiyure ezi-2. Ukunganyangeki kobushushu bexesha elide ayiphezulu, i-homopolymer i-POM yexesha elincinci kunokunyanzeliswa kwe-POM ingaphezulu kwe-10 ℃ okanye ngaphezulu, kodwa Ke. Malunga. Ingasetyenziselwa ixesha elide kuluhlu lobushushu olwenziwe kwi-90 ° C. I-POM ilula kakhulu ukubola, iqondo lokushisa lama-240 degrees ezingama-240. Ukubola kwe-Crisrication kunye neGesi yoTyhila kwenzeka, ke insimbi yokumba kufuneka inyuswe imveliso yezinto ezibonakalayo.
1, I-POM yeplastiki ye-crystalline, ukuxinana kwe-1.42G / cm3, kuhle kakhulu, ngokufuthi njengentsimbi.
2, Inokukhathala ukungakhathali, ukumelana nokunganyangeki, ukuxhathisa, ukumelana nobushushu, ukunganyangeki kwempembelelo kunye nenye indlela yokusebenza ebalaseleyo, kunye nokulingana.
I-3, i-POM akukho lula ukufunxa umswakama, inqanaba lokufumana amanzi le-0.22 ~ 0.25%, izinga lokuzinza ngendlela eyi-2%, ubungakanani bejeyile yenaliti kunokuba nzima ngakumbi ukulawula ngokuchanekileyo, ubushushu Iqondo lobushushu le-172 ℃.
Iipropathi zeplastiki zeplastiki: i-Pom amandla, ukuqina okuphezulu, ukuqina okuhle, ukunyangwa okuhle. Iipropathi zayo zoomatshini zigqwesileyo, kunokuba amandla anokufikelela kwi-50,5MPA, kunokuqina kwe-260MPA, kunye nentsimbi isondele kakhulu kwi-POM yokutshintsha kwesi siqwenga se-POM, Utshintsho lukhulu kancinci. Amandla efuthe elininzi liphezulu, kodwa ifuthe eliqhelekileyo lingaphantsi kwe-ABS ne-PC; I-POM i-notch-ivel, kukho ii-lotches zinokwenziwa kumandla empembelelo yehlile ngama-90% okukhona. Amandla okudinwa kwe-Pom ibalasele kakhulu, amandla okudinwa amandla ukuya kwi-35MPA, ngelixa i-PA kunye nePC i-28 kuphela ye-28 kuphela. I-Pom's Creep iyafana ne-PA, nge-20 ℃, i-21MPA, i-3000h yi-2.3% kuphela, kwaye kubushushu buncinci kakhulu. Into ye-Pom incinci, inxibe ukuchasana kulungile, umda wexabiso le-PV lukhulu kakhulu, ukuzithoba. Iimveliso ze-POM ngokuchasene nokugaya, umthwalo omkhulu kulula ukuvelisa ngokufanayo nengxolo enkulu.
IiPropathi zePlanethi zoMbane bePlanethi:
I-Pom yombane ilungile, iphantse ingafumaneki bubushushu kunye nokufuma; ilahleko yediliya kunye nelahleko yediliya kuluhlu olubanzi lobushushu, umngcipheko kunye notshintsho rhoqo luncinci kakhulu; Ukunganyangeki kwe-ArC elungileyo, kwaye kungagcinwa kumaqondo obushushu aphezulu.pom ahambelana nobunzima, ubukhulu be-0.127mm yi-82mm yi-82mm yi-82mm yi-82.7kv / mm, i-23.6kv / mm. I-POM ye-PROM isebenza ngokusingqongileyo: I-POM ayixhathisi kwiiarhente zomeleleyo ze-alkalis, kwaye zinozinzo oluthile kwi-acid ye-Eyeic Acid kunye ne-Aldesves, ii-anis, iioyile ezibuthathaka, njl. njl., kwaye unokugcina uzinzo lwamachiza amacwerha kumaqondo obushushu aphezulu. Ukuthathwa kwamanzi amancinci, uzinzo oluhle kakhulu. Ukuchasana kwemozulu ye-Pom akulunganga, ixesha elide kwi-ultraviolet, iipropathi zoomatshini ukwehla, umphunga wokwenza umphezulu kunye nokuqhekeka. I-POM yeplastiki yeplastiki: i-crystalline impahla, incinci yokunyibilika, ukunyibilikisa kunye nokuqina kweqondo lokushisa elisekuqaleni. Ulwelo yindawo ephakathi. Ukuthandwa komswakama kuncinci, akunakume.
I-POM eguqulweyo:
1, Ukuphucula izixhobo zokuphucula i-fiber yeglasi, ibhola yeglasi okanye i-carbon fiber, kunye ne-fiber ye-carbon, kunye neempawu zeglasi zisetyenziswa ngamaxesha ama-2 ukuya kwanga-3, ubushushu be-DureTornion bunyuke ngaphezulu kwe-50 ℃.
I-2, i-POM ecinyiweyo i-POM enganyangekiyo kwi-POM ngokudibanisa igraph, i-F4, iMolybdenum ilahlekile, i-lellybdenum ilahlekile, i-lelbust kunye ne-molekyuli ephantsi yemolekyuli. Umzekelo, ukongeza iinxalenye ezingama-5 ze-F4 kwi-POM, zinokunciphisa umxholo we-60%, nxiba ukumelana ngamaxesha oku-1 ukuya kwezi-2. Omnye umzekelo, ukongeza ioyile ye-ofisi ukuya kwi-POM inokuphucula kakhulu ukuxhathisa impahla kunye nexabiso lokugqibela le-PV. Ukwenzela ukuphucula indlela yokusasazeka yi-oyile, kufuneka yongeze ikharbon emnyama, i-aluminium hydroxide ibarfate, ye-Ethylene proplene irabha kunye nabanye abathwali ngeoli. Yongeza i-5% ye-oyile ye-oyile enyuke nge-72%, ixabiso lokugqibela le-PV ukuya kwi-3.9MPA-M / S (i-POM enyulu ye-0,213), amatye obunye ama-onji emi-3 ukuya kwengama-20.
I-Invenger ye-Pommollymer-Pom-Dupont (Delrin)
I-PEMINT's POM ihlelwa ngokucokisekileyo ngokwe-viscofity yayo: Inani lokuqala lemveliso iyondela kwisalathiso sayo, ke i-100, 300, i-900 ye-900 ye-500 eqingqiweyo Isalathiso, iphantsi i-viscosity), njengokuthelekisa kwe-viscofity: i-POM 100nc010> POM ye-900p I-900p> POM ye-900Af. I-POM 900P BK602.
