Unyuze ahantu hose hubatswe, mu isambu, cyangwa mu busitani bw'ibikoresho, uzabona amatafari ya PVC akora cyane—arinda imizigo imvura, atwikira ibyatsi byangiritse ku zuba, cyangwa ashyiraho amacumbi y'agateganyo. Ni iki gituma ibi bikoresho biramba? Si resin nini ya PVC cyangwa imyenda ikomeye gusa—ni PVC stabilizer irinda ibikoresho kwangirika mu gihe habaye ikirere kibi cyo hanze no mu bushyuhe bwinshi.
Bitandukanye n'ibicuruzwa bya PVC bikoreshwa mu nzu (urugero nka vinyl panilles cyangwa inkuta), amatafari ahura n'ibintu bidasanzwe bitera imihangayiko: imirasire ya UV idashira, ubushyuhe bukabije (kuva mu gihe cy'ubukonje kugeza mu mpeshyi ishyushye), no gupfunyika cyangwa kurambura buri gihe. Hitamo itarafari ritari ryo, maze amatafari yawe azashira, avunike, cyangwa ashire mu mezi make—biguhenda amafaranga yo kugaruza, ibikoresho byangirike, kandi utakarize abaguzi. Reka turebe uburyo bwo guhitamo itarafari rihuye n'ibyo tarafari isaba, n'uburyo rihindura inzira yawe yo gukora.
Icya mbere: Ni iki gitandukanya amatarapi?
Mbere yo kwibanda ku bwoko bw'ibikoresho bitera imbaraga, ni ngombwa gusobanukirwa icyo tarpaulin yawe ikeneye kugira ngo ikomeze kubaho. Ku bakora ibikoresho, hari ibintu bibiri bituma amahitamo y'ibikoresho bitera imbaraga:
• Kuramba hanze:Tarps zigomba kurwanya kwangirika kwa UV, kwinjiza amazi, no gushonga. Ingufu zituma tarps zihagarara neza bivuze ko zihinduka zoroshye kandi zigahinduka ibara mbere y’uko igihe cyazo cyo kubaho (ubusanzwe imyaka 2-5).
• Ubushobozi bwo guhangana n'umusaruro:Amatarapi akorwa hakoreshejwe uburyo bwo gusiga PVC mu mpapuro nto cyangwa kuyisiga ku mwenda wa polyester/pamba—ibi bikorwa byombi bikora kuri dogere selisiyusi 170–200. Ingufu zidakomeye zituma PVC iba umuhondo cyangwa ikazana utudomo hagati mu gihe cyo kuyitunganya, bigatuma ukuraho uduce twose tw’amatarapi.
Dufite ibyo bikenewe mu mutwe, reka turebe ibyo bitera imbaraga bitanga—n’impamvu.
Ibyiza kurusha ibindiIbikoresho Bidahungabanya Imiterere bya PVCku matarapi (n'igihe cyo kuyakoresha)
Nta kintu na kimwe gifasha guhagarara neza gikoreshwa kuri tarps, ariko hari amahitamo atatu ahora arusha ayandi mu gukora ibintu nyabyo.
1,Ibinyabutabire bya Calcium-Zinc (Ca-Zn): Ibyiza byose byo gukoresha Tarps zo hanze
Niba urimo gukora tarps zikoreshwa mu buhinzi cyangwa mu bubiko bwo hanze,Ibikoresho bitera imbaraga bya Ca-Znni byo byiza kurusha ibindi. Dore impamvu byabaye ikintu gikoreshwa cyane mu ruganda:
• Nta lisansi irimo, bivuze ko ushobora kugurisha lisansi yawe ku masoko y’Ubumwe bw’u Burayi na Amerika utitaye ku bihano bya REACH cyangwa CPSC. Abaguzi muri iki gihe ntibazakoresha lisansi ikozwe mu munyu wa lisansi—kabone n’iyo byaba bihendutse.
• Bikorana neza n'inyongeramusaruro za UV. Vanga 1.2–2% Ca-Zn stabilizer (ishingiye ku buremere bwa PVC resin) hamwe na 0.3–0.5% by'ibitera imbaraga z'urumuri rwa amine (HALS), kandi uzongera kabiri cyangwa gatatu ubushobozi bwa tarp yawe bwo kurwanya UV. Hari umuhinzi wo muri Iowa uherutse guhindura ubu buryo maze avuga ko tarps zabo z'ibyatsi zimara imyaka 4 aho kuba 1.
• Bituma tarps ziguma zoroshye. Bitandukanye n’ibikoresho bikomeye bituma PVC ikomera, Ca-Zn ikorana n’ibikoresho bya pulasitiki kugira ngo bigumane ubushobozi bwo gupfunyika—ni ingenzi ku tarps zigomba kuzingirwa no kubikwa igihe zidakoreshwa.
Inama y'inzobere:Shaka Ca-Zn y'amazi niba urimo gukora tarps zoroshye (nk'izo mu nkambi). Ivanga neza cyane n'imashini zikora pulasitiki kuruta ifu, bigatuma ihinduka neza muri tarps zose.
2,Uruvange rwa Barium-Zinc (Ba-Zn): Kuri Tarps zikomeye n'ubushyuhe bwinshi
Niba icyo wibandaho ari tarps zikomeye—ibipfukisho by'amakamyo, amacumbi y'inganda, cyangwa imbogamizi z'aho bubaka—Ibitera imbaraga bya Ba-Znbirakwiye gushorwamo. Utu tuvange turabagirana aho ubushyuhe n'imbaraga ari byinshi:
• Bikora neza mu gukora ubushyuhe bwinshi kurusha Ca-Zn. Iyo PVC nini (1.5mm+) ishyizwe ku mwenda, Ba-Zn irinda kwangirika k'ubushyuhe ndetse no kuri 200°C, ikagabanya impande z'umuhondo n'imigozi idakomeye. Uruganda rukora tarp muri Guangzhou rwagabanyije igipimo cy'ibisigazwa kuva kuri 12% kugeza kuri 4% nyuma yo guhindura Ba-Zn.
• Byongera ubushobozi bwo kwirinda amarira. Ongeraho 1.5–2.5% Ba-Zn mu ifumbire yawe, maze PVC ikagira isano ikomeye n'inyuma y'imyenda. Ibi ni ibintu bihindura umukino ku makamyo akururwa hejuru y'imizigo.
• Bihuye n'ibintu bigabanya inkongi z'umuriro. Amatarapu menshi yo mu nganda agomba kuba yujuje ibisabwa mu kwirinda inkongi z'umuriro (nka ASTM D6413). Ba-Zn ntabwo ihura n'inyongera zigabanya inkongi z'umuriro, bityo ushobora gukubita ibimenyetso by'umutekano udatakaza ubusugire.
3,Ibikoresho Bidakora ku Isi Bidasanzwe: Ku byerekeye Tarps zo Kohereza mu mahanga zigezweho
Niba ugamije amasoko yo ku rwego rwo hejuru—nk'amatafari y'ubuhinzi yo mu Burayi cyangwa amacumbi yo kwidagaduriramo yo muri Amerika ya Ruguru—ibintu bito bigabanya ubushyuhe bw'ubutaka (uruvange rwa lanthanum, cerium, na zinc) ni byo byiza. Birahenze kurusha Ca-Zn cyangwa Ba-Zn, ariko bitanga inyungu zikwiriye ikiguzi:
• Ihindagurika ry’ikirere ridasanzwe. Ibikoresho bito birwanya imirasire ya UV ndetse n’ubukonje bukabije (kugeza kuri -30°C), bigatuma biba byiza cyane ku bikoresho bikoreshwa mu misozi miremire cyangwa mu majyaruguru. Ikigo cy’ibikoresho byo hanze cyo muri Kanada kibikoresha mu bikoresho byo mu nkambi kandi kivuga ko nta ngaruka zabonetse bitewe n’ubukonje buterwa no gucikamo ibice.
• Kubahiriza amahame agenga ibidukikije. Nta byuma biremereye kandi byujuje amabwiriza akomeye y’Umuryango w’Ubumwe bw’Uburayi ku bicuruzwa bya PVC "byangiza". Iyi ni ingingo ikomeye ku baguzi bifuza kwishyura amafaranga menshi ku bicuruzwa birambye.
• Kuzigama amafaranga mu gihe kirekire. Nubwo ikiguzi cyo gutangira ari kinini, ibikoresho bigabanya ihindagurika ry’ubutaka bigabanya gukenera kongera gukoreshwa no kugaruza. Mu gihe cy’umwaka, inganda nyinshi zibona ko zizigama amafaranga ugereranyije n’ibikoresho bigabanya ihindagurika ry’ikirere bitera ibibazo by’ubuziranenge.

Uburyo bwo gutuma Stabilizer yawe ikora neza (Inama z'ingirakamaro mu kuyitunganya)
Guhitamo imashini ihamye ikwiye ni kimwe cya kabiri cy'intambara—kuyikoresha neza ni kimwe cya kabiri. Dore amayeri atatu aturuka ku bakora tarp b'inararibonye:
1. Ntukarenze urugero
Birashishikaje kongeramo imashini igabanya ubushyuhe “kugira ngo ubeho neza,” ariko ibi bipfusha ubusa amafaranga kandi bishobora gutuma imashini zikomera. Korana n'umucuruzi wawe kugira ngo ugerageze igipimo gito cy'ingirakamaro: tangira kuri 1% kuri Ca-Zn, 1.5% kuri Ba-Zn, kandi uhindure ukurikije ubushyuhe bw'umusaruro wawe n'ubugari bwa tarp. Uruganda rwa tarp rwo muri Megizike rwagabanyije ikiguzi cya stabilizer ho 15% rugabanya gusa igipimo kuva kuri 2.5% kugeza kuri 1.8%—nta kugabanuka k'ubwiza.

2,Shyira hamwe n'inyongera za kabiri
Ibikoresho bitera imbaraga bikora neza hamwe n’ibifasha mu gukingira. Ku mavuta yo hanze, ongeramo amavuta ya soya ya epoxidized (ESBO) angana na 2–3% kugira ngo wongere ubushobozi bwo koroshya no kurwanya ubukonje. Ku bijyanye no gukoresha UV nyinshi, vangamo agace gato ka antioxydant (nka BHT) kugira ngo wirinde kwangiza ibintu bitera imbaraga. Ibi birungo birahendutse kandi bigwizaho ubushobozi bwa stabilizer yawe.
3,Isuzuma ry'ikirere cyawe
Tarp igurishwa muri Florida ikeneye uburinzi bwinshi bwa UV kurusha iyagurishijwe muri leta ya Washington. Kora ibizamini bito: shyira ingero za tarp ku rumuri rwa UV rwifashishijwe (ukoresheje icyuma gipima ikirere) mu gihe cy'amasaha 1.000, cyangwa ushyire muri firigo ijoro ryose urebe niba zacitse. Ibi bituma imvange yawe ihuza n'isoko wifuza.'imiterere.
Ibikoresho Bidahungabanya Bisobanura Tarp Yawe'Agaciro
Amaherezo, abakiriya bawe ntibita ku kintu gitera imbaraga ukoresha—bitayeho ko icyo gikoresho cyabo kiramba mu mvura, izuba n'urubura. Guhitamo icyo gikoresho gitera imbaraga gikwiye cya PVC si ikiguzi; ni uburyo bwo kubaka izina ryiza ku bicuruzwa byizewe. Waba ukora ibikoresho by'ubuhinzi bihendutse (ukoresha Ca-Zn) cyangwa ibikoresho by'inganda bigezweho (ukoresha Ba-Zn cyangwa rare earth), ikintu cy'ingenzi ni uguhuza icyo gikoresho n'icyo gikoresho cyawe.
Niba utazi neza uburyo bwo kuvanga ibintu bikubereye, saba abatanga ibikoresho bigufasha gupima ibintu. Bagerageze mu buryo bwo gukora, ubashyire mu bikorwa mu buryo bufatika, kandi ureke ibisubizo bikuyobore.
