Gutangira kwishyiriraho igorofa, ikibazo kivuka ibikoresho byimiyoboro nibyiza: adoda polyethylene cyangwa plastiki.
Igisubizo kiri mubihe bikora igorofa, kandi ibitekerezo byinzobere, uburambe no gusuzuma abantu bakorera hasi sisitemu yo gushyushya hasi bazafasha gukemura iki kibazo.
Hashingiwe ku miyoboro hafi ya zose zigezweho, idoda polyethyylene, gusa ibigize icyuma-plastike-plastike ibyuma byo hanze hamwe nimbere bya polyethylene bihuza igice cyicyuma gikora monolith yibicuruzwa.
Yadoda Polyethylene: Ibintu
Bitewe na molecular yinyongera ya molekile ya polyethylene ifite imbaraga nyinshi
Gudoda Polyethylene bivuga ibikoresho byikoranabuhanga bihanitse kandi ni umusaruro wamasatsi wa Ethylene ufite imiterere ya mesh molekelar hamwe na rex ahinnye.
Mubisanzwe, inzira yo kudoda ni ugukora umubano winyongera. Gutangira Polymer ifitanye isano no kumwanya wa molekic hamwe niminyururu yubusa ya molekile, ikora gride eshatu, imiterere ikomeye hamwe na "ingaruka zo kwibuka".
Ibicuruzwa bimwe byose nibyiza
Impinduka mubunini nuburyo bwumuyoboro uyoboye imizigo nyuma yo kuvanaho ibicuruzwa muburyo bwumwimerere. Ukurikije imitungo ya tekiniki, Rex ntabwo iri munsi yibintu byinshi kandi irenze mubuzima bwa serivisi.
Imiyoboro idoda polyethylene itanga inzira 4:
- Peroxide yatangijwe muri polyethylene mu gukora ibikoresho. Urwego rwo hejuru rwo guhura ni 75%. Muburyo bwo gutanga umusaruro muke nigiciro kinini cyibicuruzwa, ariko ibikoresho biba biramba cyane kandi biramba.
- RE -HB - Gutunganya ubuhehere hamwe na Silane na Catalyst bitera Polyethylene, aho igikonoshwa kidakomeye, ariko mugihe amazi yanyuze, irashobora kwihanganira igitutu kinini. Kudoda ni 65%.
- Rech - c - Polymer ivurwa na electron. Polyethylene ufite urwego rwo hasi rwo guhura na 55 - 60%.
- Rh - xd - acide ya nitric ikoreshwa. Uburyo budakoreshwa.
Y'uburyo bwashyizwe ku rutonde, umuyoboro wakozwe hamwe no gukoresha Silane urakenewe cyane, urangwa nigiciro cyiza nibikorwa byemewe.
Ingingo ku ngingo: Gutegura Plaster-ishingiye kuri plaster
Ubwoko bwiza bwa pipe for igorofa rishyushye ryakozwe na polyethylene ni ibicuruzwa bibiri bya re kandi o-xBine hamwe nigice cyo kurinda, kikaba ari inzitizi ya ogisijeni ikwirakwizwa na polyethylene.
Ibyiza bya polyethylene
Umuyoboro mubikoresho nkibi bifite molekile
Imiyoboro yo gushyushya ikoreshwa nuburyo re-ha-xb iraranga:
- Kurwanya igitutu gitonyanga. Muburyo bwo hejuru, ubuzima bwibicuruzwa ntabwo buhinduka. Polymer yihanganiye igitutu kugeza kuri 10.
- Kwibuka moleki. Iyo amazi yakonje mumuyoboro, urubura rwavuyemo rwongera diameter yumuyoboro, hanyuma nyuma yo gukinisha urubura, ubunini bwumuyoboro usubira muri verisiyo yumwimerere, nta kwangiza ibikoresho.
- Gushonga no gutwika ubushyuhe bwo hejuru. Ibikoresho bizashonga ku bushyuhe burenga 150 ° C, no gutwika mugihe ubushyuhe bw'imboro bugera kuri 400 ° C.
- Kurwanya imiti n'ibinyabuzima. Umuyoboro wa Polyethylene ntugengwa nuburyo bwo kugakona, ntabwo bitanga imiterere yo kugaragara kwa fungi no kubyara, ibikoresho byarwanya chlorine kandi bikomeza kutagira aho tubogamiye mu mazi ya chlorine.
- Umutekano wibidukikije. Ibikoresho mugihe cyo gushyushya ntabwo byangiza ibintu byangiza kandi bigacana kuri dioxyde de karuboni namazi mugihe yaka.
Polyethylene ntatinya itandukaniro ryubushyuhe
- Plastiki. Hamwe no kunama inshuro nyinshi, ibicuruzwa ntibiturika kandi bigarura ubunini bwurugo.
- Imikorere. Ibikoresho bya polymer bigumana imitungo, ntibifungure ubunini bwumuyoboro ufite ubushyuhe bwa coolant kuva 0 kugeza 95 ° C, ariko ibikoresho birashobora kwihanganira kandi ubutegetsi bukomeye bwubushyuhe.
Ibyuma bya plastike: Ibintu
Ibyiza byo guhumeka polyethylene nabyo bifite umuyoboro-cya plastiki ugizwe nibice bitanu, buri kimwe muricyo gikora imirimo imwe. Ibice byo hanze nibice bya polymeric, hamwe nigikonoshwa cyo hanze gikora uburinzi bwo kwirinda amashanyarazi, kandi urwego rwimbere rugira uruhare mu miyoboro y'amazi yihuta.
Igice cyimbere ntabwo gikora inzitizi kumazi
Hano hari ibice 2 bifatika hagati yubucuruzi bwa polymer, kandi hagati - urwego rwimbere ni urwenya rufite umuco utanga igishushanyo mbonera cyicyuma-plasike.
Kwizerwa no kuramba mubikorwa byibicuruzwa-bya plastike bigena ireme ryibice:
- Igice cya aluminium kigena imbaraga zacyo kandi kigomba kuba umubyimba byibuze mm 3. Uburyo 2 bwo gusudira urwego rwa aluminium rugira ingaruka kumuyoboro wumuyoboro, guhagarika laser muburyo bwo gusudira kandi ultrasonic gusudira yumuringa ni tekinoroji yakoreshejwe. Uburyo bwo gusudira igice cya Jack bwitwa Concess, ntabwo bufite uburiganya no kugereranya no gusumura wacompande ntabwo byemerera kumeneka ahantu hahujwe na fittings.
- Ibikorwa byakoreshejwe bigena ibara rishoboka ryibice ku bushyuhe bwa gukonjesha, nabyo bigira ingaruka ku mbaraga z'umuyoboro. Ku muyoboro wo gukata mugihe ukoresheje kole-ubuziranenge, bundle irabuze.
- Kwizerwa k'umuyoboro bigenwa n'ibice bya polymer, polymer hamwe na pex na pe-IT ikimenyetso cyemeza imbaraga z'umuyoboro, naho imiyoboro ifite ikindi cyiciro ikoreshwa na polymer yo hasi, muri iyi sano, n'umuntu wa hydraulic.
Mugihe duhitamo umuyoboro wicyuma, dusuzumye ko ibyo bicuruzwa bifite uburyo budafite akamaro bwo gusudira urwego rwa aluminium, rutanga imikorere yubusa.
Guhitamo imiyoboro y'amazi
Gerageza guhitamo ibikoresho byiza
Ibyifuzo byinshi nibicuruzwa, hamwe nuwabikoze, muriki gihe igikorwa ni kimwe, guhitamo formula nicyo giciro cyiza / ubuziranenge, ariko ni ngombwa gutangirana nubuziranenge:
- Umuyoboro wizewe nimbaraga zubukanishi mugihe ukoreshwa mubihe byihariye, bizatuma gahunda yubuntu itangiriye ibibazo mugihe cyo gukora, I.e. Umuyoboro ugomba kwihanganira igitutu cyibura 10.
- Ubuzima bwa serivisi cyangwa kuramba bwo gukoresha sisitemu yo hasi biterwa nibikoresho bivuye aho ibicuruzwa bikozwe. Imyuga yumuyoboro ntiyemewe ku bushyuhe bwa coolant 95 ° C.
- Kuburyo bwubusa binyuze mumiyoboro ya coolant, ubuso bwimbere bwumuyoboro bugomba kuba bworoshye.
- Ibisabwa kugirango kubungabunge, ibiciro byo gukumira no kugenzura ibizamini bya sisitemu yo gukomera ni byiza. Soma byinshi kubyerekeye imiyoboro yo guhitamo, reba muriyi video:
Ibiranga uburyo bwo gushyushya butangwa nisoko, akazi gakomeye ko kwishyiriraho hamwe nibisabwa gukora birasuzumwa nyuma yo gusuzuma ibintu byujuje ubuziranenge. Icya nyuma ariko, tugereranya ikiguzi cyibicuruzwa, kwizirikana akazi ko kwishyiriraho, kimwe nikibazo hamwe nigikoresho cyigenga gishyushye.
Kugereranya ibiranga imiyoboro hamwe na diameter ya mm 20

Icyuma cya plastike kidagereranije na polyilene
Byose kimwe, ni ubuhe bwoko bwiza burushaho gushyuha: polyethylene cyangwa ibyuma. Itandukaniro ryibicuruzwa mubice bya polyethlene yambukiranya umuyoboro wa pulasitike hamwe nicyuma.
Kunoza Polymer, abahanga ndetse n'inzobere mu murima wa chimie bashoboye guhindura Poloyeti hamwe n'izina risanzwe pe - Rt, aho imiterere ikundana n'amashami ya molekile. Polymer ntabwo ibura imitungo mugusubiramo, bitandukanye nabanjirije. Ibyifuzo byinzobere muguhitamo imiyoboro reba muriyi video:
Imiyoboro kuva PE - RT Polyethylene numutwe ukomeye wa coolant witandukanya urusaku rwamazi. Polymer irenze cyane idoda ya polyethlene irwanya igitutu kinini nubushyuhe bwa coolant, kimwe nigihe cyumuyoboro.
Bitewe n'imiterere ya molekile hamwe n'amashami y'amashami, ibikoresho bya PE birinda imiyoboro, imiyoboro irashobora gupfobya no gusudira nta turere twangiritse.
Ibikoresho bihanganye nubukonje bwinshi kandi bukomanga udahinduye imiterere numutungo. Ibikoresho bya Pe-RT bitanga ibicuruzwa byombi hamwe nicyuma-plastike.
Ubushyuhe bwa Pe - RT Polymer mumitungo yayo yujuje ibyangombwa byo hasi kandi birashobora gufatwa nkibintu byiza mugihe uhisemo imiyoboro myiza.
Ingingo kuri iyo ngingo: igikoresho inkuta kuri bkoni
