Umatshini we-theminal yekhemikhali ye-Polyoxyylene (Pom)

Iipropathi ezisisiseko zePolyxolothylene (Pom)

I-paramifoldeolEyihy i-polymer ye-polymer enendawo ephezulu yokunyibilika, uxinzelelo oluphezulu, i-crystalline, iqulathe -Chelis kwi-molecule ngaphandle kwembonakalo yecala elimhlophe okanye ekhanyayo. Inokwahlulwa yangamacandelo amabini: enye yi-copololly yeparaformaldehyde kunye nenani elincinci leDioxane, elibizwa ngokuba yiCopolyformalmehydehyde; Enye into yi-homopolymer ye-fomuldehyde okanye iparafoldehyde, ebizwa ngokuba yi-homopolymer yeparaformahyde. Nangona kukho umahluko kulwakhiwo lweentlobo ezimbini zeparaformaldehyde, kodwa umyinge we-CC kwi-molelyformalmermalmehyde incinci kakhulu (i-3% ukuya kwi-5%), ukusebenza kwezi ntlobo zimbini zeparafoleddes ziyafana , banempawu ezifanayo.

2. Iipropathi zoomatshini

I-paraformaldeolE yi-crystalline ye-crystalline, enesimo sengqondo esiphakamileyo se-elastity, ubunzima obukhulu, ubunzima obuninzi, bunokujamelana neempembelelo eziphindaphindiweyo, zinokuba kwi-40 ~ 100 ℃ kusetyenziso lwexesha elide.

I-crystallity yeparaminalEldeoldedde ingaphezulu kwe-70%, ngaloo ndlela inesidima esihle sokungakhathali. Yeyona nto iphambili yokungakhathali phakathi kwezinto ze-thermoveristicisticicicicisticitisticisticicicicicisticisticicicicies, kwaye ifaneleke ngakumbi kwiimveliso zegiya ngokuxhomekeke kumandla angaphandle aphindaphindiweyo kunye neenxalenye eziqhubekayo.

Ukuxhathisa i-culyfolmalEaldehyde kuyafana ne-Polyamide kunye nezinye iiplanga zobunjineli, kwaye ixabiso layo lobunjineli litshintsha kancinci liqondo lobushushu, ukuya kuthi ga kwiqondo lobushushu eliphezulu, i-Creep ihleli ilungile. Kwi-23 ℃, i-21MPA ilayista, emva kwexabiso le-3000 cerp li-2.3% kuphela.

Amandla abuhlungu e-PolyfolDaldehyde inkulu, kwaye amandla ahlambelele kwiimolekyuli uphezulu, ke ukunyangwa kulungile. Into engxamisekileyo kwaye inxibe inani le-polyfolfaldehyde incinci, kwaye ixabiso le-PV likhulu, ke lilungele iindlela zexesha elide. Kwaye iipropathi zayo zokuzithoba ziyindawo engenalo ioyile engacacanga okanye ethambekele kwi-oyile yokuqala yendalo ephantsi kokukhetha izinto ezixineneyo, zibonelela ngexabiso elikhethekileyo, i-polyfolyehhhhydes njengezinto ezintsha zokungena kwiindawo ezahlukeneyo.

3. Iipropathi ze-thermal

I-PolyfoldEldehyde inomsindo ophezulu wobushushu obuyi-124 ° C kwi-homopolyformalthelehyde kunye ne-110 ° C yeCopolyformalmehyde. Iqondo lokungcola kobushushu leparaformaldehyde liphezulu kuneyona nto yeCopolyfolneformalmehyde, kodwa uzinzo lwe-thermal yeparafoldeonaldeonaldeonaldeonaldeolsefolfolmehyde. Ngokubanzi, iqondo lokushisa ixesha elide lokusebenzisa iParaformalEoldehyde limalunga ne-100 ℃. Idatha yepropathi ephambili ye-polyfoldEldehyde iboniswe kwiTheyibhile 1-1. I-PolyfolEaldehyde iya kuvelisa inqanaba elithile lokufuma kunye nokwaluphala kwamanzi ngamanzi ashushu, kwaye inkonzo yayo yokuphila emanzini ashushu iphantsi kune-moya eshushu.

4. Iipropathi zombane

I-Acetal ineepropathi ezifanelekileyo zombane, ilahleko yeDeectric incinci, i-voltage yokuqhekeka iphezulu, ukunyangwa kokufakelwa i-102 ~ 105hz kunye ne-20 ~ Uluhlu, i-dielectric rhoqo ye-acetaldehyde igcinwa kwinqanaba le-3.1 ~ 3.9. I-Diecric Angle Tangent inayo imeko efanayo: Xa iqondo lokufumana amanzi linyuka ukusuka kwi-0.2% ukuya kwi-0.8%, ilahleko ye-Anglecric Angle ye-Angle ye-Tanger enyuka kuphela malunga ne-0.003. Iipropathi zombane zeparaformalEldehyde ziboniswe kwiTheyibhile ye-1-1.IPROCTURE ephezulu yombane weparaformaddehyde ayilunganga kakhulu. Njengoko iqondo lobushushu liyanda, i-dielectric rhoqo kwaye ilahleko ye-dislectric tangent yonyusa kakhulu. Ke ngoko, kwiShishini le-elektroniki ephezulu, ngakumbi ishishini le-Eltra-Righ-Righ-Righ-Rest-Right Services kufuneka liqatshelwe xa kusetyenziswa.

I-voltage ye-paraminalEldehyde iphakame, kwaye ukumelana kwawo kumdlalo we-ARC omkhulu kakhulu. Kwi-ARC eyomileyo kunye nothuli kunye novavanyo lwe-FOO, ayivelisi imikhondo yokuvuza kunye nekharbhonization. 5.

5. Ukuxhathisa kwemichiza

Ukuxhathisa iikhemikhali zeparaformalEdde resin iboniswe kwiTheyibhile 1-2. Isakhiwo esisisiseko separaformalEddeDE ichaza ukuba ayinawo i-solver yobushushu yegumbi. Apha ngezantsi okanye kufutshane nendawo yokunyibilika ye-resin, phantse ayinakwenzeka ukufumana nasiphi na isolvent, kwaye kuphela izinto ezifana ne-perfluorocerocenocetone. Ke ngoko, kuwo onke amakhohlatha kubunjineli kwindawo yePolyfoldEmaddehbooldDesitible kwizinyithi zendalo kunye nokuchasana kweoyile kubalaseleyo. Ingakumbi kulawulo lobushushu obuphezulu lunengxaki yokukhukuliseka okuhle, kwaye ubungakanani kunye namandla omatshini wotshintsho abuphakathi.

I-polyformalEAlDehyde isukelowe ilunge ngakumbi ukuxhathisa i-acids, kodwa i-acid eqinileyo, ingakumbi i-sulfuric acid, i-witric acid, i-witric acid, njl.

Ngenxa yokuqulunqwa kwesiphelo esivalekileyo iHomomisolDaoldehyde iya kuba yi-Alkali kwiQela le-Acid, ilandelwa ngokulandelelana kwe-formaldehymehyde, ke i-alkali ye-colyformalEolfalmehyde. Ngokubanzi, kukhuselekile ukusebenzisa i-homopolyformalmehyde kuphela kwisisombululo se-alkali ngexabiso le-PH lingaphantsi kwe-10.

Amandla okukhulisa amathafa obunjineli ukuya emanzini anokukhokelela kutshintsho olunemveliso kwimveliso, ngelixa utshintsho oluveliswayo oluveliswe kukungena kwamanzi kwi-parafoldehyde kakhulu kwaye ungazenzi ingxaki kwizicelo ezisebenzayo.

6. Ukusetyenziswa kwePolyxolothylene (Pom)

Kumzi-mveliso woomatshini, iparafoldehyde isetyenziswa ngokubanzi ekwenzeni iigiya, iirowu, ii-cams, i-gols, i-gols, i-golbles, i-spings, njl. isetyenziswe njengeeNdawo zokuHanjiswa kwamandla ngokubanzi. I-paraformalEoldeddedde esetyenzisiweyo ekwenzeni i-bushings, iigiya, izilayidi kunye nezinye ze-oyile, ziphucule i-oyile yentsimbi, kwaye ke zinokuba luluhlu olubanzi lweendlela ezizezinye ngalo Ubhedu, i-zinc kunye nezinye izinyithi zokuvelisa ibherings, iigiya, iintonga ze-tie njalo njalo. Into eguqulweyo ye-PolyfolfolEmilEAlEHolDhehyde incinci, ingqongqo eqinileyo, ilungele kakhulu ukuvelisa iipumps, iinxalenye ze-carbures, imigca ye-carling, izixhobo zokwenza izixhobo, iSoftware yeWindows, iShishini yoMbane ibhanti lebhanti kunye ne-qho. Kwizixhobo ze-elektroniki, iparaformaldehyde isetyenziswa ekwenzeni iinxalenye zezixhobo ezahlukeneyo zombane, ezinje nge-Wrench Shell, isiphatho sokutshintsha, njl., Kunye nezinto zombane zekhaya kumalungu; Kwindawo yokwakha yokwenziwa kweefreyimu zefestile, iibhafu zokuhlamba, iitanki zamanzi, iingcango zamanzi, ii-picleys kunye ne-pulales, njalo njalo.
