Amakuru

Mu rwego rw'imodoka ruhora rutera imbere, pulasitiki yoroheje yahindutse ikintu gishya. Bitewe no gutanga igipimo cyo hejuru cy'imbaraga hagati y'uburemere, imiterere y'ibikoresho, no kugabanya ikiguzi, pulasitiki yoroheje ni ingenzi mu gukemura ibibazo bikomeye by'inganda byo gukoresha neza lisansi, kugabanya imyuka ihumanya ikirere, no kuramba. Ariko, nubwo ibi bikoresho bifite inyungu nyinshi, binazana n'imbogamizi zihariye. Muri iyi nkuru, tuzasuzuma ibintu bikunze kubangamira ikoreshwa rya pulasitiki yoroheje mu nganda z'imodoka kandi dutange ibisubizo bifatika bishobora kongera imikorere no kugabanya ikiguzi cy'umusaruro.

Plasitiki zoroshye ni iki?

Plasitike yoroheje ni polymeri zifite ubucucike buke, nka polyethylene (PE), polypropylene (PP), polystyrene (PS), acrylonitrile butadiene styrene (ABS), polycarbonate (PC), na polybutylene terephthalate (PBT), ubucucike buri hagati ya 0.8–1.5 g/cm³. Bitandukanye n'ibyuma (urugero: icyuma: ~7.8 g/cm³), izi plastiki zigabanya uburemere zitagize ingaruka ku miterere y'ingenzi ya mekanike cyangwa ubushyuhe. Amahitamo agezweho nka pulasitiki zikozwe mu ifuro (urugero: polystyrene yagutse, EPS) n'ibice bya thermoplastic bigabanya ubucucike mu gihe bikomeza imiterere y'imiterere, bigatuma ziba nziza mu gukoresha imodoka.

Imikoreshereze ya Plastiki zoroheje mu nganda z'imodoka

Plastike yoroheje ni ingenzi mu gushushanya imodoka zigezweho, bigatuma abakora imodoka babasha kugera ku ntego z'imikorere, imikorere myiza, no kubungabunga ubuzima. Porogaramu z'ingenzi zirimo:

1. Ibice by'imbere mu modoka:

Ibikoresho: PP, ABS, PC.

Porogaramu: Amadirishya yo ku meza, inzugi, ibice by'intebe.

Akamaro: Yoroshye, iramba, kandi ishobora guhindurwa kugira ngo irusheho kuba nziza kandi igire ihumure.

2. Ibice byo hanze by'imodoka:

Ibikoresho: PP, PBT, PC/PBT.

Porogaramu: Bumpers, grilles, indorerwamo.

Ibyiza: Kurwanya ingaruka, kwihanganira ikirere, no kugabanya uburemere bw'imodoka.

3. Ibice biri munsi y'inyuma y'inyuma:

Ibikoresho: PBT, polyamide (nylon), PEEK.

Ibikorwa: Ibipfukisho bya moteri, ama-manifolds y'umwuka ajyana umwuka, n'ibihuza.

Ibyiza: Kurwanya ubushyuhe, kudahindagurika mu binyabutabire, no kuba umuhanga mu bipimo.

4. Ibice bigize imiterere:

Ibikoresho: PP cyangwa PA byashyizwemo ikirahure cyangwa fibre ya karuboni.

Ibikoresho: Gukomeza chassis, amasahani ya bateri ku modoka zikoresha amashanyarazi (EVs).

Ibyiza: Ifite imbaraga nyinshi hagati y’uburemere n’uburemere, irwanya ingese.

5. Gukingira no Gushyiramo ubushyuhe:

Ibikoresho: Ifuro rya PU, EPS.

Imikoreshereze: Imitako y'intebe, amapine y'urusaku.

Ibyiza: Ingufu zoroheje cyane, zifata neza cyane.

Mu modoka zikoresha amashanyarazi, pulasitiki yoroheje ni ingenzi cyane, kuko igabanya uburemere bw'imodoka zikoresha bateri ziremereye, bigatuma indege igenda neza. Urugero, aho bateri zikoresha PP n'ibikoresho bya PC bigabanya uburemere mu gihe bikomeza kubahiriza amahame y'umutekano.

Ibibazo n'ibisubizo bisanzwe ku bikoresho bya pulasitike byoroheje mu ikoreshwa ry'imodoka

Nubwo hari ibyiza byazo, nko gukoresha neza lisansi, kugabanya imyuka ihumanya ikirere, koroshya imiterere, gukoresha neza ikiguzi, no kongera gukoresha ibikoresho, pulasitiki zoroshye zihura n'imbogamizi mu mikoreshereze y'imodoka. Hasi hari ibibazo bikunze kugaragara n'ibisubizo bifatika.

Ikibazo cya 1:Uburyo bwo gushwanyagurika no kwangirika mu bikoresho bya pulasitiki by'imodoka 

Ikibazo: Ubuso bwa pulasitiki yoroheje nka Polypropylene (PP) na Acrylonitrile Butadiene Styrene (ABS), bukunze gukoreshwa mu bice by'imodoka nka dashboards n'inzugi, bushobora gushwanyagurika no gushwanyagurika uko igihe kigenda gihita. Ubu busembwa bw'ubuso ntibugira ingaruka gusa ku bwiza bw'ubwiza ahubwo bushobora no kugabanya kuramba kw'ibice, bigasaba kwitabwaho no gusanwa by'inyongera.

Ibisubizo:

Kugira ngo iki kibazo gikemuke, gushyiramo inyongeramusaruro nka silicone-based plastic additives cyangwa PTFE mu buryo bwa pulasitiki bishobora kongera cyane uburambe bw'ubuso. Iyo wongeyeho 0.5–2% by'izi nyongeramusaruro, ubushyuhe bw'ubuso buragabanuka, bigatuma ibikoresho bidakunda gushwanyagurika no gushwanyagurika.

Bitewe n'ubwinshi bw'inganda zikora inyongeramusaruro za silikoni zihari, ni ibihe bipimo wakoresha kugira ngo uhitemo umufatanyabikorwa mwiza mu bucuruzi?

Muri Chengdu Silike Technology Co., Ltd., twibanda kuinyongeramusaruro za pulasitiki zishingiye kuri siliconeyagenewe kunoza imiterere ya Thermoplastics na Engineering plastics zikoreshwa mu modoka. Ifite uburambe bw'imyaka irenga 20 mu guhuza silicone na polymers, SILIKE irazwi nk'umufatanyabikorwa ukomeye mu guhanga udushya n'umufatanyabikorwa wizewe mu mikorere myiza.gutunganya ibisubizo by'inyongeramusaruro n'ibihindura.

Ibyacuinyongeramusaruro za pulasitiki zishingiye kuri siliconeibicuruzwa byakozwe by'umwihariko kugira ngo bifashe abakora polimeri:

1) Kunoza igipimo cyo gusohora no kugera ku buryo buhoraho ku byuma bito.

2) Kongera ubwiza bw'ubuso n'ubushyuhe, bifasha mu gutuma ibihumyo birekura neza mu gihe cyo kubitunganya.

3) Kugabanya ikoreshwa ry'ingufu no kugabanya ikiguzi cy'ingufu bitabaye ngombwa guhindura ibikoresho bikoreshwa mu gutunganya ibikoresho.

4) Inyongeramusaruro zacu za silikoni zihuye cyane n'ubwoko bwinshi bwa thermoplastics na pulasitiki z'ubuhanga, harimo:

Polypropylene (PP), Polyethylene (HDPE, LLDPE/LDPE), Polyvinyl Chloride (PVC), Polycarbonate (PC), Acrylonitrile Butadiene Styrene (ABS), Polycarbonate/Acrylonitrile Butadiene Styrene (PC/ABS), Polystyrene (PS/HIPS), Polyethylene Terephthalate (PET), Polybutylene Terephthalate (PBT), Polymethyl Methacrylate (PMMA), Nylon (Polyamides, PA), Ethylene Vinyl Acetate (EVA), Thermoplastic Polyurethane (TPU), Thermoplastic Elastomers (TPE), n'ibindi.

Ibiinyongeramusaruro za siloxanebinafasha mu guteza imbere ubukungu bushingiye ku ruziga, bigatera inkunga abakora ibikoresho mu gukora ibintu birambye kandi byujuje ibisabwa ku bidukikije.

SILIKE Silicone Wax SILIMER 5235: Uburyo bushya bwo kunoza ubuso kugira ngo habeho uburyo bwo kunoza imirasire

Birenze ibisanzweinyongeramusaruro za pulasitiki zishingiye kuri silicone, SILIMER 5235, naishashi ya silikoni yahinduwe na alkyl,Iragaragara cyane. Yagenewe by'umwihariko ibikoresho bya pulasitiki byoroshye cyane nka PC, PBT, PET, na PC/ABS, SILIMER 5235 itanga ubushobozi bwo kwirinda gushwanyagurika no kwangirika. Mu kongera ubushyuhe ku buso no kunoza irekurwa ry'ibihumyo mu gihe cyo gutunganya, ifasha kugumana imiterere n'ubworoshye bw'ubuso bw'igicuruzwa uko igihe kigenda gihita.

Imwe mu nyungu z'ingenzi zaishashi ya siliconeSILIMER 5235 ni nziza cyane ijyanye na resins zitandukanye za matrix, igenzura ko nta mvura cyangwa ingaruka ku buryo bwo gutunganya ubuso. Ibi bituma iba nziza ku bice by'imbere by'imodoka aho ubwiza bw'ubwiza no kuramba ari ngombwa.
