Pom, cyangwa polyoxymethylene, ni inzira yimikorere yo mu rwego rwo hejuru ihindura inganda. Byari ubwambere byaganje muri 1920 ariko byacukuwe gusa muri 1950.
Ibi bikoresho bidasanzwe bihatiye imbaraga zidasanzwe, guterana amagambo, no gushikama. Kuva mu bice by'imodoka n'ibikoresho by'ubuvuzi, pom ni uguhindura igishushanyo mbonera no gukora.
Muri iyi nyandiko, tuzakemura ubwoko bwa pom, imitungo, porogaramu, ibyiza, ibibi, guhindura nuburyo bifatika.
Plastike ni iki?
Polyoxymethylene (pom) , nanone yitwa Acetal , Polyacetal , cyangwa Polyformaldehyde , ni umuhanga mikorere miremire mu .
Imiterere ya molekolexymethylene (pom)
Imiterere ya molekolexymethylene (pom) ishingiye ku bice byo gusubiramo formaldehyde monomers . Izi monomers zigizwe na atome ya karubone ihuza amatsinda abiri -or . Imiterere ya pom irashobora koroshya kuri formula (Ch₂o) n , ikora iminyururu miremire ya polymer.
Iyi miterere yoroshye ariko ifatika ibisubizo muri kimwe cya kabiri . Hafi ya karina yayo ndende itanga pom imbaraga nuburinganire. Iminyururu ya polymer ipakiye hamwe, biganisha ku gipimo gishimishije hamwe no kwinjiza mu buryo buke.
Ingingo z'ingenzi z'imiterere ya Pom:
Gusubiramo ibice bya Ch₂o (formaldehyde).
Igice cya kamere yongera ibintu byubukanishi.
Gupakira Polymer Gupakira byambaza imbaraga nimbaraga.
Iyi nyubako yemerera pom gukomeza imikorere miremire mubidukikije aho ibisobanuro no kwihangana ari ngombwa.
Ubwoko bwa pom plastike
Hariho ubwoko bubiri bwingenzi bwa plastike: Pom homopolymer (pom-h) na pom copolymer (pom-c) . Byombi bitanga ibyiza byihariye bitewe nibisabwa, ariko biratandukanye mumiterere n'imikorere.
Pom homopolymer (pom-h)
Pom-h ikozwe muri monomer imwe, igatanga imiterere isanzwe ya Crystalline . Iyi singstalinine iganisha ku miterere ikomeye . Birakomeye, gukomera, kandi birashobora gukemura hejuru cyane kandi imitwaro yo kwikuramo . Niba gusaba kwawe bisaba imbaraga nyinshi kandi nkeya zinyeganyega, pom-h ni amahitamo akomeye.
Ibintu by'ingenzi biranga pom-h:
Imbaraga za Tensile nziza : Ibyiza kubice bitwara imitwaro.
Inono cyane : Hagarara kugirango wambare kandi urire.
Guhagarara neza : Gumana imiterere mubidukikije.
Pom copolymer (pom-c)
Ku rundi ruhande, pom-c yaremye na polyémbising monomers ebyiri zitandukanye. Ibi bituma birushaho kurwanya imitambi kandi bikamuha umutekano mwiza kuruta pom-h. Ntabwo bikunze guteranya uburozi, bitezimbere kuramba, cyane cyane mubidukikije bitose. Pom-c nayo ikora neza muburyo bwa alkaline.
Ibintu by'ingenzi biranga pom-c:
Ibyiza byo kurwanya imiti : Nibyiza guhura nibibazo, ibicanwa, n'imiti.
Kunoza kurwanya hydrolysis : ikora neza mubushuhe buremereye.
Umutekano wo mu bushyuhe : uhangane n'ubushyuhe bwo hejuru.

Ibyiza bya Polyoxymethylene (pom)
Polyoxymethylene (pom) yahawe agaciro kubwinyungu zidasanzwe, bituma bige-ibikoresho munganda nyinshi. Hano hari inyungu zingenzi zerekana impamvu pom itandukanye.
Imbaraga nyinshi-kuri-uburemere
Pom azwiho imbaraga zidasanzwe mugihe asigaye mubwibone . Iyi mpirimbanyi ituma itungantego kuri porogaramu aho kugabanya imbaraga haba kunegura binegura, nkibice byimodoka hamwe nimashini zinganda.
Guterana hasi no kwambara
Ikintu kimwe gikubiyemo pom ninganiza bike byo guterana amagambo . Uyu mutungo ugabanya cyane wambara no kurira muri porogaramu zirimo kunyerera cyangwa kuzunguruka , nk'ibikoresho n'ibikoresho. Nibikoresho byonyine, byongera kuramba mugusaba ibidukikije.
Umutekano
Pom ikomeza gushikama cyane ndetse no mubushyuhe bwimvura nurwego rwabohore. Ibi biranga bituma bituma bitunganya ibice byuburinganire, byemeza ibikoresho bifite imiterere nubunini mugihe, nikibazo mubisabwa byinshi.
Kurwanya imiti n'ubushuhe
Pom yerekana kurwanya imiti nubushuhe , cyane cyane mubidukikije bya alkaline. Ikurura amazi mato cyane, bigatuma habaho guhitamo kwizewe kubisabwa birimo ibintu bitose cyangwa imiti nkibisanzwe nkibishusho na valves.
Korohereza imashini
Imwe mu mpamvu zitoneshwa nababikora nuburyo bworoshye bwo gufata . Irashobora gucukurwa, gukinisha, no guhindurwa neza, bikagumaho neza kugirango ushyireho ibice bifatika.
Inshinge nziza z'amashanyarazi
Pom atanga amashanyarazi akomeye , kubigira ibikoresho byatoranijwe kubice byamashanyarazi. Imitsi yacyo ifasha kurinda sisitemu ya elegitoroniki kuva mu mashanyarazi, bigatuma ari ingirakamaro ku guhindura, gutanga, no guhuza.
Kwikuramo ibintu
Ndashimira kamere yayo yo kwibeshya , pom igabanya ibikenewe byo hanze muri sisitemu ya mashini. Uyu mutungo, uhujwe n'amakimbirane make, afasha kwagura ubuzima bwibihuru nka bushings nabambuzi.
Ubwiza bushimisha hejuru
Birenze imikorere, pom itanga hejuru yuburyo bworoshye . Ubworoherane bwayo kandi bworoshye butuma bikwirakwira mubice byagaragaye , cyane cyane mubicuruzwa byabaguzi nibishushanyo byinganda bisaba isura isenyutse.
Amafaranga yubahiriza FDA arahari
Kunganda nk'ibiribwa no gutunganya ibiryo , pom itanga amanota ya FDA-Yubahiriza . Izi ngeso zifite umutekano kugirango duhuze neza nibikoresho nibikoresho byubuvuzi, tubike kubahiriza ibipimo byumutekano.

Ibibi bya Polyoxymethylene (pom)
Mugihe pom plakiyeni itanga inyungu nyinshi, izanye ibibi byinshi bigomba gufatwa nkibisabwa.
Umukene UV
Umupaka umwe ukomeye wa pom ni ukurwanya umucyo wa UV . Iyo uhuye nizuba ryizuba kubihe byagutse, birashobora gutesha agaciro, biganisha ku guhindura, kwari ukwambika imbaraga, no gutakaza imbaraga. Niba UV yongeye kwerekana, uv stabilizars irakenewe.
Kurwanya imiti
Nubwo pom irwanya imiti myinshi, ishobora kwibasirwa nigisigi ikomeye . Hafi yo guhura n'imiti ikaze irashobora gutera imbaraga, gukora pom bike bikwiye kubidukikije bikaze huti yimiti idafite ingamba zidasanzwe.
Ubushyuhe bugarukira
Pom irashobora gutesha agaciro ubushyuhe bwinshi adafite intandaro nziza. Gukomeza guhura nubushyuhe burenze imipaka birashobora kuganisha ku guhungabana no kugabanya imikorere yubukanishi. Nibyiza kubara inzitizi yubushyuhe mugusaba porogaramu.
INGORANE ZIKURIKIRA
POM ifite imbaraga zo hejuru , zitera guhuza cyangwa gutya zigoye nta kuvura hejuru. Uburyo budasanzwe nuburyo bwo gutegura busabwa gushyiraho umubano ukomeye hagati yiposita nibindi bikoresho, bishobora kugorana inzira yo gukora.
Kugabanuka cyane muburyo bwo kubumba
Mugihe cyo kubumba, pom erekana agabanutse cyane , bishobora kugira ingaruka kubwukuri. Abakora bakeneye kugenzura witonze igishushanyo mbonera no gukonjesha kugirango bishyure iki kibazo, cyane cyane mugusaba.
Ibitekerezo byafashwe
Pom nihenze cyane kuruta plastidity yibicuruzwa byinshi. Iki giciro cyo hejuru gishobora kuba ikintu muguhitamo ibikoresho kumisaruro rusange, cyane cyane mugihe gikwiye cyane.
Kumurika cyane udafite ibiti bya flame
Pom iraka cyane muburyo busanzwe. Hatariho abategetsi ba Flame, birashobora gutwikwa byoroshye, kandi ko hasohora imyuka yubumara. Mubikorwa hamwe nibisabwa umutekano ukomeye, uburyo bwinyongera burakenewe.
