Intangiriro ku nsinga za PVC zidafite umwotsi mwinshi n'insinga zikoreshwa mu gukwirakwiza insinga

Insinga za PVC (Polyvinyl Chloride) n'insinga zikozwe mu buryo bwa thermoplastic zikozwe mu rwego rwo kugabanya umwotsi n'imyuka ihumanya mu gihe cyo gutwika. Ibi bituma ziba amahitamo y'ingenzi mu bikorwa aho umutekano w'inkongi ari ingenzi. Ubusanzwe zikoreshwa mu gukingira no gupfuka insinga z'amashanyarazi, izi nganda zifite ibintu byinshi by'ingenzi:

Imiterere:Ibinyabutabire bya PVC bidakoresha umwotsi mwinshi bikozwe hifashishijwe uruvange rwa PVC resin, plasticizers (nk'iya dioctyl phthalate na tri-2-ethylhexyl trimellitate), ibintu bigabanya umuriro (urugero: antimony trioxide, aluminium trihydrate, na zinc borate), ibintu bitera imbaraga (bishingiye kuri calcium/zinc), ibintu bitunganya (calcium carbonate), n'amavuta.

Imiterere y'umwotsi muke:Bitandukanye na PVC isanzwe, ishobora kugabanya ubushobozi bwo kubona kugeza kuri 90% mu minota 30 gusa bitewe n'umwotsi mwinshi, utwuma duto twa PVC twakozwe kugira ngo twuzuze amahame y'umutekano nka BS EN 61034. Utwo tuyumu tureka nibura 60% by'urumuri mu gihe cyo gutwika, binongera cyane umutekano.

Gutinda k'umuriro: PVC ifite ubushobozi bwo kudakoresha umuriro bitewe n'ingano ya chlorine, ikaba yongeraho ibindi bikoresho bigabanya umuriro. Ibi bikoresho byujuje ibisabwa nka IEC 60332-1-2, UL VW1, na E84 (ikimenyetso cyo gukwirakwiza umuriro <25, ikimenyetso cyo gukwirakwiza umwotsi <50).

 Porogaramu:Insinga za PVC n'insinga zikoreshwa cyane mu bice bishobora guteza akaga nko mu bigo bitanga amakuru, mu mihanda, mu ndege, mu magare ya gari ya moshi, no mu nyubako rusange, ni ingenzi cyane mu kugabanya ibyago biterwa n'umwotsi n'imyotsi ihumanya mu gihe habayeho inkongi.

Ibibazo bikunze kugaragara mu gutunganya insinga za PVC n'insinga zikoresha insinga nkeya

Gutunganya imvange za PVC zidafite umwotsi mwinshi bikubiyemo gukemura ibibazo bitandukanye, cyane cyane bitewe n'uburyo zikorwamo bugoye. Hasi aha, turaganira kuri bimwe mu bibazo bikunze kugaragara mu gutunganya imvange n'ibisubizo byazo:

1. Ibikubiye mu bipimo byinshi bitera kutagenda neza no kutagira umuvuduko mwinshi w'amashanyarazi

Ikibazo:Kugira ngo umwotsi ugabanuke, imvange za PVC akenshi ziba zifite urugero rwo hejuru rw’ibice bidafite umwimerere nka aluminium trihydrate (ATH) cyangwa magnesium hydroxide (Mg(OH)₂) — ubusanzwe 20-60% by’uburemere. Nubwo ibi bice bigabanya umwotsi n’umuriro, bishobora kongera ubushyuhe, kugabanya uburyo bwo gutemba, no gutuma ibikoresho byangirika.

Ibisubizo:

Shyiramo ibikoresho byo gutunganya nk'amavuta yo mu nzu/yo hanze (urugero: calcium stearate, polyethylene waxes, cyangwainyongeramusaruro za silikoni) kuri 0.5-2.0 phr kugira ngo bigabanye ubushyuhe no kongera urujya n'uruza rw'amazi.

Koresha ibikoresho byo gusohora ibikoresho bifite uburebure bwa L/D bwinshi kugira ngo uvange neza kandi ushyiremo neza ibintu.

Koresha uburyo bwo gukanika bukoresha imbaraga zifatana kugira ngo urebe ko buvangavanga neza.

Hitamo ibikoresho byo kuzura bifite ingano y’uduce twagenzuwe n’uburyo bwo kuvura ubuso kugira ngo birusheho guhuza neza no kugabanya kwangirika.

2. Guhagarara neza kw'ubushyuhe

Ikibazo:PVC ishobora kwangirika mu gihe cyo gutunganya, cyane cyane iyo irimo kuzuza byinshi no gukurura umuriro, ikarekura umwuka wa hydrogène chloride (HCl) bigatera kwangirika kw'ibikoresho, guhinduka ibara, no kwangirika kw'ibikoresho.

Ibisubizo:

Shyiramo ibintu bigabanya ubushyuhe nka calcium/zinc-based stabilizers kuri 2-4 phr kugira ngo uhagarike HCl kandi wirinde kwangirika.

Koresha amavuta ya soya ya epoxidized (ESO) nk'ikintu gifasha mu kunoza ubushyuhe no gupima ubushyuhe.

Genzura ubushyuhe butunganywa neza (160-190°C) kugira ngo wirinde ubushyuhe bwinshi.

Shyiramo antioxydants za phenolic (urugero, Bisphenol A kuri 0.3-0.5%) kugira ngo wongere ubushobozi bwo kudasaza mu gihe cyo gutunganya.

3. Kwimura pulasitiki

Ikibazo:Imashini zikoresha pulasitiki zikoreshwa mu kongera ubushobozi bwo koroshya ibintu zishobora kwimuka mu gihe cy'ubushyuhe bwinshi (urugero, mu bigo bitanga amakuru), bigatuma ibisigazwa byiyongera bishobora kubangamira uburyo bwo kohereza ibimenyetso cyangwa bikagabanya igihe kirekire cy'insinga.

Ibisubizo:

Koresha pulasitiki za polymeri zitajya zimuka aho gukoresha izo muri monomeric (urugero, DOP, DINP) kugira ngo ugabanye ukwimuka.

Kora formula za plenum "zitagira amazi", nk'uko byateguwe na OTECH, kugira ngo hirindwe ko pulasitiki yimuka mu bidukikije birimo ubushyuhe bwinshi.

Hitamo ibikoresho bya pulasitiki nka TOTM, bifite imihindagurikire mike kandi bikwiranye cyane no gukoreshwa mu bushyuhe bwinshi.

4. Kurinda ubushyuhe bw'umuriro no gukumira umwotsi

Ikibazo:Kongera ubushyuhe bw'umuriro binyuze mu birungo nka antimoni trioxide (3-5%) cyangwa ibinyabutabire bya bromine (12-15%) bishobora kongera imyuka y'umwotsi, bigatuma bigorana kuringaniza imiterere yombi. Mu buryo nk'ubwo, ibirungo nka calcium carbonate bishobora kugabanya umwotsi ariko bishobora kugabanya igipimo cya ogisijeni, bigatera ubushyuhe bw'umuriro.

Ibisubizo:

Koresha imvange ihuza umuriro (urugero: ATH hamwe na zinc borate) kugira ngo wongere ubushobozi bwo kugabanya umuriro no gukumira umwotsi. Urugero, ATH irekura umwuka w'amazi kugira ngo ihagarike umuriro kandi ikore urwego rw'uburinzi, rugabanya umwotsi.

Gabanya umutwaro wa CaCO₃ ku gipimo cya 20-40 phr kugira ngo ubone uburinganire hagati y'ikiguzi, kugabanya umwotsi, no kudakora neza kw'inkongi z'umuriro, kuko ingano irenze urugero ishobora kugabanya igipimo cya ogisijeni.

Suzuma imiterere ya PVC ishobora guhuza, nka PVC ifite imirasire ihuza, kugira ngo wongere ubushobozi bwo kudakoresha umuriro utishingikirije cyane ku bikoresho bya halogen.

5. Uburyo bwo gutunganya no kunoza ubuso

Ikibazo:Ibyuma byinshi byo kuzura no kongeramo inyongera bishobora gutuma ubuso budakora neza, amazi agabanuka, ndetse no gusohora ibintu mu buryo budasobanutse neza, ibyo bigira ingaruka ku miterere n'imikorere y'insinga ya nyuma.

Ibisubizo:KoreshaIfu ya silikoni ya SILIKE LYSI-100AIbiinyongeramusaruro ishingiye kuri siliconeikoreshwa cyane nk'ikintuinyongeramusaruro nziza yo gutunganya amavutaku buryo bwo gutunganya resin bujyanye na PVC kugira ngo hongerwe imiterere yo gutunganya resin n'ubwiza bw'ubuso bwayo. Nk'uburyo resin ishobora gutemba neza, kuzuza no kurekura ibumba, imbaraga nke zo gusohora, hamwe n'ubushobozi buke bwo gukururana, ubwiyongere bw'ingufu no kudakuramo...

Ibyiza by'ingenzi bya silicone Powder LYSI-100A ku bikoresho bya PVC no ku bikoresho bya nyuma:

1) Insinga za PVC n'insinga zirimo umwotsi muke: gusohora amazi mu buryo buhamye, umuvuduko muke w'amashanyarazi, ubuso bworoshye bw'insinga n'insinga.

2) Insinga za PVC n'insinga zidafite ubukana bwinshi: Korejiyo nke yo gukururana, kumva neza igihe kirekire.

3) Igikoresho cya PVC kidashwaragurika: Kirinda gushwaragurika, nk'uko bimeze mu byuma bifunga PVC.

4) Imiterere ya PVC: kuzuza neza ibihumyo no kurekura ibihumyo, nta gushyuha kw'ibihumyo.

5) Umuyoboro wa PVC: umuvuduko wo gusohora vuba, COF yagabanutse, ubuso burushaho koroha, kandi amafaranga agabanuka.

Niba uhura n'ibibazo byo gutunganya PVC hamwe n'ubusembwa bw'ubuso, cyangwa uhanganye no gutunganya insinga za PVC zidakoresha umwotsi mwinshi, geragezaIfu ya Silicone ya LYSI-100A ifasha mu gutunganya neza no kunoza imikorere.
