Impamvu imikorere y'icyuma gikozwe muri pulasitiki ari myiza kurusha imikorere y'icyuma gikozwe muri pulasitiki

 

1. Iterambere ry'ingufu za pulasitiki

Muri iki gihe, abakiriya benshi ni na n'ubu niteguye guhitamo icyuma gikoreshwa mu ibikoresho. N'ubundi kandi, iyo imigozi ya pulasitiki itakorwaga, imigozi y'icyuma yakoreshwaga nk'ibikoresho gakondo. Ariko kugeza ubu, imikorere y'ibyuma bya pulasitiki izaba myiza kurushaho mu gihe kizaza.

2.Ibikoresho bya pulasitiki n'ibindi inyungu

TIgiciro cyo gukora pulasitiki kiri hasi ugereranyije n'icyiciro cy'ibyuma, kandi ubwoko bw'ibikoresho bya pulasitiki buriyongera cyane. naikoreshwa mu nganda nyinshiibikoresho bisanzwe bya pulasitikini nylon, polytetrafluoroethylene, polyethylene na PEEK.

Itsinda amapine ya pulasitiki is Uburyo bwo gukora ibintu bitandukanye, ubukungu n'isuku. Hari ibikoresho byinshi bihendutse biboneka mu bikorwa bitandukanye. Ubusanzwe, ibyuma bya pulasitiki bikozwe mu byuma bikoresha thermoplastic bifite fibre matrix n'amavuta akomeye, bifite imbaraga nziza kandi bifite friction coefficient ntoya kandi ihoraho.

3. Ni iyihe mikorere myiza y'ibyuma bya pulasitiki? ?

(1) Kwisiga amavuta

Plasitike's Imiterere y’umubiri, ishyira amavuta ku matwi, igabanya gutinda gutangira kandi igatuma agace kadakora neza. Agace gato k’amatwi karambara ku ntangiriro kandi kakagira uruhare mu gusiga amavuta ku matwi, ariko impinduka y’amatwi ubwayo ishobora kwirengagizwa. Ibi kandi bituma amatwi ya pulasitiki aba meza cyane mu ikoreshwa ry’ibiribwa, kuko FDA ibuza cyane ikoreshwa ry’amavuta mu mashini zikora ibiribwa. Byongeye kandi, nubwo umukungugu n’ibindi bice bizaguma ku matwi maze bigakora urwego rw’umwanda, ku matwi ya pulasitiki, ibice ibyo ari byo byose bizashyirwa mu matwi kandi ntibizagira ingaruka ku mikorere.

(2) Gukora ku bushyuhe buri hasi kandi buri hejuru

Ibyuma bya pulasitiki bishobora gukora buri gihe ku bushyuhe ubwo aribwo bwose buri hagati ya -4° C na 260° C kandi ishobora kwihanganira ubushyuhe bwinshi kugeza kuri dogere 600° F. Igitereko cya pulasitiki gishobora gukomera nk'igitereko cy'icyuma, ariko ikirango Urukuta ni ruto, ubusanzwe rufite ubugari bwa 0.0468 "- 0.0625". Inkuta zoroshye zitanga uburyo bwiza bwo gusohora ubushyuhe, bigatuma imikorere irushaho kuba myiza kandi ikagabanuka. Byongeye kandi, inkuta zoroshye ziba zoroshye kandi ntizishobora kwangirika, bigatuma zikoreshwa mu gihe cy'ibibazo by'uburemere.

(3) Imikorere y'ibidukikije

Kubera uburemere bworoheje bwa pulasitiki, ibyuma bya pulasitiki bikoresha lisansi neza. Ibikoresho bya pulasitiki ntibisaba ibindi bisigazwa cyangwa ibindi bivangwa kugira ngo bitange umusaruro nk'uw'ibice by'icyuma bisanzwe byuzuzwa n'ibintu byangiza. Byongeye kandi, gukora pulasitiki bisaba amavuta agera kuri 10-15% gusa ugereranije n'ingano imwe ya aluminiyumu cyangwa icyuma.

(4) Ubudahangarwa bwiza bw'imiti

Ubusanzwe, ibyuma bikingira ibyuma birwanya imiti n'ibindi bintu bitandukanye kurusha ibyuma bikingira ibyuma, kandi birwanya gushwanyagurika no kwangirika kw'ibyuma bikingira ibyuma. Ibi bifasha kugumana ubwinshi bwabyo bwo gushwanyagurika no kugenda neza nta nkomyi nyinshi.

(5) Ingufu zitagira ubwikorezi

Hitamo pulasitiki ikwiye ukurikije aho ikoreshwa, kandi icyuma gishobora kwirinda ingese uko igihe kigenda gihita. Nyuma yo kuyishyiraho, icyuma gifata pulasitiki kimara igihe kirekire kandi ntigikeneye gusimburwa. Ingese ishobora gutuma ibyuma bifata icyuma bikonjesha aho biri, bigatuma bidashoboka kubikuraho utabiciye. Ibyuma bifata pulasitiki biroroshye kubikuraho.

(6) Igiciro gito cya pulasitiki

Plasitiki nyinshi zirahendutse kurusha ibyuma. Bityo rero, imiringoti ya pulasitiki n'udukingirizo twa pulasitiki bishobora kugabanya ikiguzi
