　　Ukukhethwa kweplastiki zobunjineli ngesicelo esithile kuhlala kuqhutywa kwindawo yayo yokusebenza, kunye ne-Polyoxythylene, inikezela ngeprofayili ye-Acetal, ibonisa ukuba uninzi lwabantu abaninzi bagqibe kwelokuba bangakulungelanga kwabanye. Idume ngamandla ayo aphakamileyo, ukuqina, uzinzo olusezantsi, izinto eziphantsi kwe-POM, i-PHICH ye-SICTION SICOST, i-POM SICSE YOKUGQIBELA, EMVA KOKUGQIBELA, EMVA KOKUSETYENZISWA KWEXESHA LOKUZIPHATHA KWI-CHEMICEUUI iyadibana. Ukuqonda imeko yokuxhathisa i-Pom ayisiyonto yokudweliswa kunye nokungahambelani neekhemikhali; Ifuna umbulelo kwisakhiwo sePolymer yePolymer kunye neendlela apho iiarhente zekhemikhali ezahlukeneyo zinokuqalisa ukonakaliswa, ezinjengokudumba, ukuqhekeza, okanye ilahleko yentlekele yeepropathi zoomatshini. Olu lwazi luphazamiseka iinjineli kunye nabaqulunqi bokwenza izinto ze-POMS ETRANY POIM

　　Kwisiqhelo, i-POM ibonakalisa ukungaxhathisi okhethekileyo kuluhlu olubanzi lwee-hydrocarbons, izinyibilikisi eziphilayo, kunye nezikhephethi, ezenza isiseko sombane sayo esibanzi kwi-Automotive, kwiZimilo zoMatshini, kunye nemizi-mveliso yoomatshini. Ibonisa uzinzo olwenziweyo ngokuchasene ne-Aliphatic hydrocarbles, kubandakanya i-fuels njenge-petroli nedizili, ioyile, iitoyithi, kunye nezinyibilikisi, kunye nezinyibilikisi ezifana nomoya omhlophe. Oku kwenza ukuba ibe yinto efanelekileyo yecandelo lenkqubo yamafutha, i-Petrol CAPS, kunye neenxalenye ezisebenza kwiindibano ezibiweyo. Ngaphaya koko, i-POM ibambelela kwi-alcolol eninzi, kuquka ne-ethanol kunye ne-Iyopropanol, ngakumbi kubushushu begumbi, kunye ne-ecenes, iiKetne ezinesiphumo esincinci. Ukuxhathisa kwayo kwii-Acids ezibuthathaka kunye neziseko zilungile kakhulu, zivumele ukuba zenze ngokuthembekileyo xa zivezwe zizinto ezinje ngeZisombululo ze-ACKECO ZE-ACKIC okanye iAlkaline apho uxinzelelo kunye neqondo lobushushu lihlala lihlala liphakathi khona. Lo mbonakalo uqhelekileyo obanzi kulwelo oluqhelekileyo lwemizi-mveliso, ludityaniswe neempawu zalo ezibalaseleyo zendlela, yinto eqinisa isikhundla se-POM njengeemeko ezifuna ukuchaneka kunye nokuqina kwendawo ezinomngeni.

　　Nangona kunjalo, amandla anokuphazamiseka kokumelana kweekhemikhali ze-Pom ayinamsebenzi obalekayo obalekayo, ngokuyintloko kwii-acids ezomeleleyo kunye neziseko ezomeleleyo. Ukuvezwa kukugxininiswa kwe-inorneid ye-Inorganic acid, enje nge-sulfuric acid, kunye ne-hitric acid, kuya kukhokelela kwi-polymer ekhawulezileyo nebukhali yePolymer. Iimolekyuli ze-asidi zihlasela unxibelelwano lwe-volymer kwi-polymer, ebangela ukungafihlisi kwinkqubo ye-polymerizazazazaza-ekhokelela kwilahleko ye-molecur kunye nokugquma okuhambelana namandla e-subile kunye nokunyaniseka okufanayo. Ngokufanayo, izisombululo ze-caustic ezomeleleyo, njenge-sodium ye-sodium hydroxide, inakho ukuphelisa i-Pom, ngakumbi kumaqondo obushushu aphakamileyo. Elinye isoyikiso eliphambili livela kwiiarhente zokudideka. I-Halogens injenge-chlorine kunye ne-bromine, kunye nee-oxidizers ezinje nge-hydrogen peroxide okanye i-chlorine diokside, inokubangela ukonakaliswa kwe-oxibalive, kukhokelela ekulweni. Mhlawumbi enye yeyona ibaluleke kakhulu, kwaye ngamanye amaxesha igqitywe, ubungozi buya kukhanya kwe-ultraviolet. I-Pom engafezekisiyo inamandla amakhulu kukuba nexhala xa iyonakalisa xa ityhilwe ukwexesha elapha ngokuhamba kwexesha; Nasiphi na isicelo sangaphandle, amabakala e-UV-I-IV-STATILL SET kufuneka icaciswe ukuthintela imicimbi yokuqhubela phambili kunye nelahleko yepropathi.

　　Ukusetyenziswa kolu lwakhiwo kudlulela ngaphaya koluhlu olulula lwe-binary "olulungileyo" kunye "neekhemikhali" ezimbi ". Iimeko zehlabathi zokwenyani zazisa izinto eziguquguqukayo, ubushushu obubaluleke kakhulu kunye noxinzelelo oluzinzileyo. Ikhemikhali enokuthi inyamezele kubushushu begumbi ukuveza kwexesha elifutshane kunokubangela ukudumba okukhulu okanye uxinzelelo lwamaqondo obushushu aphakamileyo, thetha i-80 ° C okanye ngaphezulu. Umzekelo, ngelixa i-POM ichaze amanzi kubushushu begumbi, ukuvezwa kwexesha elide kumanzi ashushu ngaphezulu kwe-60 ° Can kungakhokelela kwi-hydrolysis, inkqubo apho iimolekyuli zamanzi ziqhekeza imixokelelwane yePolymer. Olu luqwalaselo olubalulekileyo lwamacandelo akwizixhobo okanye iinkqubo zokulinganisa. Ngapha koko, ubukho boxinzelelo oluzinzileyo loomatshini, olunjengomthwalo oguqukayo, lunokukhawulezisa uhlaselo lwekhemikhali kwi-phecomenon eyaziwa ngokuba yimbambano. Inxalenye ye-POM ephantsi komthwalo inokusilela xa ityhilwe kwikhemikhali eyangenzakalisa kwisampulu engafakwanga. Ke ngoko, kuvavanywa phantsi kwemeko ezilinganisa eyona ndawo ikwinkonzo yokwenyani-kubandakanya uxinzelelo lwekhemikhali, ubushushu, kunye nomthwalo woomatshini-kucetyiswa ngamandla kwizicelo ezibalulekileyo. Le ndlela esebenzayo ivumela ukuqinisekiswa kokukhethwa kwezinto okanye ukuchongwa kwangexesha kwesidingo sendlela enye, enje nge-ptfe ukuba ixhaphake kakhulu okanye i-PPs yeqondo lamaqondo aphezulu kunye nokuzinza kweqondo lobushushu.

　　Ukuqukumbela, ukufaneleka kwephepha le-POM yendawo ekunikeni ikhemikhali ngumbuzo wokuthelekisa amandla ayo obhalwe kakuhle ngokuchasene nemiceli mngeni ethile, eneengxaki yesicelo. Ukunganyangeki kwayo kwi-hydrocarblens, izinyibilikisi, kunye neekhemikhali ezingathathi hlangothi zenza intshatsheli kwimimandla yomatshini kunye nemoto. Ukanti, ukugwetywa kwayo kwii-Asidi zeZimbiwa eziqinileyo, iziseko ezinamandla, iiarhente ezinamandla, kunye ne-UV ukukhanya kuyalela imida ecacileyo yokusetyenziswa kwayo. Isigqibo sokugqibela masingaziswe nje nje ngokwasazisi sekhemikhali, kodwa ngokuquka iimeko zokusebenza, kubandakanya uxinzelelo, ubushushu, ubude bokuvezwa, kunye nobukho balo naluphi na uxinzelelo lonxibelelwano. Ngokujonga ngocoselelo ezi zinto, iinjineli zinokuchaza ngokuzithemba i-Pom apho iya kuthi ithintele kwaye iphephe ukuba izibonelelo zayo zendalo zifezekisiwe ngokupheleleyo ebomini.
