Hamba kuyo nayiphi na indawo yokwakha, ifama, okanye iyadi yezothutho, kwaye uya kubona iiseyile zePVC zisebenza nzima—zikhusela imithwalo emvuleni, zigquma amabhali efula ekonakalisweni lilanga, okanye zenza iindawo zokuhlala zethutyana. Yintoni eyenza la mahashe aqhubeke? Akunjalo nje i-resin eqinile ye-PVC okanye i-backings eyomeleleyo yelaphu-yi-stabilizer ye-PVC egcina izinto eziphathekayo zingabikho phantsi kweemeko ezinzima zangaphandle kunye nokuveliswa kobushushu obuphezulu.
Ngokungafaniyo neemveliso ze-PVC zokusetyenziswa kwangaphakathi (cinga i-vinyl flooring okanye iipaneli zodonga), iiseyile zijongene neseti ekhethekileyo yoxinzelelo: imitha ye-UV engapheliyo, ukuguquka kobushushu obugqithisileyo (ukusuka ebusika obubandayo ukuya ehlotyeni elitshisayo), kunye nokusonga rhoqo okanye ukolula. Khetha i-stabilizer engalunganga, kwaye i-tarps yakho iya kutshabalala, iqhekeke, okanye ixoke kwiinyanga-kuxabisa imbuyekezo, izinto ezilahlekileyo, kwaye ulahlekelwe yithemba kubathengi. Makhe sichaze indlela yokukhetha isizinzisi esihlangabezana neemfuno zeseyile, kwaye siyiguqula njani inkqubo yakho yokuvelisa.
Okokuqala: Yintoni eyenza iTarpaulins yahluke?
Ngaphambi kokuntywila kwiintlobo zokuzinzisa, kubalulekile ukuqonda ukuba yintoni efunekayo iseyile yakho ukuze uphile. Kubavelisi, izinto ezimbini ziqhuba ukhetho lokuzinzisa:
• Ukuqina kwangaphandle:Iitarp kufuneka zimelane nokuqhekeka kwe-UV, ukufunxwa kwamanzi, kunye ne-oxidation. Isizinzi esisilelayo apha sithetha ukuba iitarp zijika zibe brittle kwaye zibe nombala ixesha elide phambi kwexesha elilindelekileyo lokuphila (ngokuqhelekileyo iminyaka emi-2-5).
• Ukomelela kwimveliso:Iitarpaulini zenziwe nge-calendering ye-PVC ibe ngamashiti amancinci okanye i-extrusion-coating kwi-polyester / ilaphu lekotoni-zombini iinkqubo zihamba kwi-170-200 ° C. I-stabilizer ebuthathaka iya kubangela ukuba i-PVC ibe tyheli okanye iphuhlise amabala phakathi kwemveliso, kukunyanzela ukuba ulahle iibhetshi zonke.
Ngezo mfuno engqondweni, makhe sijonge ukuba zeziphi iziqinisekiso ezizisayo-kwaye ngoba
EgqibeleleIzizinzi zePVCiiTarpaulins (Kwaye Uzisebenzise nini).
Akukho “ubukhulu obunye-bulingana-bonke” ukuzinzisa kwiitarps, kodwa iindlela ezintathu ezikhethwayo zihlala zigqwesa ezinye kwimveliso yehlabathi lokwenyani.
1,Imidibaniso yeCalcium-Zinc (Ca-Zn): I-All-Rounder yeeTaphu zangaphandle
Ukuba wenza iitarp zenjongo yezolimo okanye yokugcina ngaphandle,Izizinzisi ezihlanganisiweyo zeCa-ZnUbhejo lwakho lungcono. Nasi isizathu sokuba baye baba sisiseko sefektri:
• Azinalothe, nto leyo ethetha ukuba ungazithengisa ii-tarps zakho kwiimarike ze-EU kunye ne-US ngaphandle kokukhathazeka malunga nezohlwayo ze-REACH okanye ze-CPSC. Abathengi kule mihla abayi kubamba iitarps ezenziwe ngeetyuwa ezikhokelayo-nokuba zingabizi.
• Zidlala kakuhle kunye nezongezo zeUV. Xuba i-1.2–2% ye-Ca-Zn stabilizer (esekelwe kubunzima be-resin ye-PVC) kunye ne-0.3-0.5% ethintele i-amine light stabilizers (HALS), kwaye uya kuphinda kabini okanye kathathu ukuxhathisa kwe-UV ye-tarp yakho. Ifama yase-Iowa isandula ukutshintshela kulo mxube yaza yaxela ukuba ihay tarps yayo yahlala iminyaka emi-4 endaweni ye-1.
• Zigcina iitarp zibhetyebhetye. Ngokungafaniyo ne-stabilizers eqinile eyenza i-PVC ibe lukhuni, i-Ca-Zn isebenza kunye ne-plasticizers ukugcina ukugotywa-okubaluleke kakhulu kwiitarps ezifuna ukusongwa kwaye zigcinwe xa zingasetyenziswa.
Ingcebiso yePro:Yiya kulwelo lwe-Ca-Zn ukuba wenza iitarps ezikhaphukhaphu (ezifana nezo zokukhempisha). Ixuba ngokulinganayo kunye neeplasticizers kuneendlela zomgubo, iqinisekisa ukuguquguquka okungaguqukiyo kuyo yonke itarp.
2,I-Barium-Zinc (Ba-Zn) Imixube: YeeTaps zoMsebenzi oMnzi kunye nobushushu obuphezulu
Ukuba ugxininiso lwakho luxanduva olunzima lweetarp-zigqubuthelo zelori, iindawo zokuhlala zamashishini, okanye izithintelo zesiza sokwakha—Ba-Zn zizinzisizilufanele utyalo-mali. Le mixube ikhanya apho ubushushu kunye noxinzelelo luphezulu:
• Baphatha imveliso yobushushu obuphezulu kuneCa-Zn. Xa i-extrusion-coating ye-PVC engqindilili (1.5mm+) kwilaphu, i-Ba-Zn inqanda ukuthotywa kwe-thermal nakwi-200 ° C, ukusika kwiindawo ezimthubi kunye nemithungo ebuthathaka. Umenzi wetarp wolungiselelo e-Guangzhou wehlise amazinga okulahlwa ukusuka kwi-12% ukuya kwi-4% emva kokutshintshela kwi-Ba-Zn.
• Zongeza ukuxhathisa kweenyembezi. Yongeza i-1.5-2.5% ye-Ba-Zn ekuqulunqweni kwakho, kwaye i-PVC yenza ibhondi eyomeleleyo kunye nenkxaso yelaphu. Lo ngumdlalo wokutshintsha iitarp zelori ezitsalwa zibhuqe phezu kwempahla
• Ziyahambelana nezithinteli zomlilo. Iitarp ezininzi zoshishino kufuneka zihlangabezane nemigangatho yokhuseleko lomlilo (njenge-ASTM D6413). I-Ba-Zn ayisebenzi ngezongezo ezithintela umlilo, ngoko unokubetha amanqaku okhuseleko ngaphandle kokuncama uzinzo.
3,Izinzinzisi zoMhlaba eziNqabileyo: NgeeTerephu zokuThumela ngaphandle kwePremium
Ukuba ujolise kwiimarike eziphezulu-njengee-tarps zezolimo zaseYurophu okanye iindawo zokuhlala zokuzonwabisa zaseMntla Melika-i-stabilizers ezinqabileyo zomhlaba (umxube we-lanthanum, i-cerium, kunye ne-zinc) yindlela yokuhamba. Baxabisa kakhulu kuneCa-Zn okanye iBa-Zn, kodwa bazisa izibonelelo ezithethelela iindleko:
• Ubume bemozulu obungahambelaniyo. Izinzisi zomhlaba ezinqabileyo zixhathisa zombini imitha ye-UV kunye nokubanda okugqithisileyo (ukuya kuthi ga kwi -30 ° C), zizenze zilungele iitarps ezisetyenziswa kwimozulu yealpine okanye emantla. Uphawu lwegiya langaphandle laseKhanada lizisebenzisa ukwenza iitarp zokukhempisha kwaye lixela imbuyekezo enguziro ngenxa yokuqhekeka okunxulumene nokubanda.
• Ukuthotyelwa kwemigangatho engqongqo ye-eco. Azinazo zonke iintsimbi ezinzima kwaye ziyahlangabezana nemithetho engqongqo ye-EU yeemveliso zePVC “eziluhlaza”. Le yeyona ndawo iphambili yokuthengisa kubathengi abazimisele ukuhlawula ngaphezulu iimpahla ezizinzileyo
• Ugcino lweendleko zexesha elide. Ngelixa iindleko zangaphambili ziphezulu, iziqinisekiso zomhlaba ezinqabileyo zinciphisa isidingo sokuphinda kusetyenzwe kunye nembuyekezo. Ngaphezu konyaka, abavelisi abaninzi bafumanisa ukuba bonga imali xa kuthelekiswa nezizinzisi ezingabizi kakhulu ezibangela imiba yomgangatho.
Indlela yokwenza isizinzi sakho sisebenze nzima (Iingcebiso eziSebenzayo zeMveliso).
Ukukhetha i-stabilizer efanelekileyo isiqingatha sokulwa-ukuyisebenzisa ngokuchanekileyo esinye isiqingatha. Nanga amaqhinga amathathu avela kubavelisi betarp abanamava:
1. Musa ukusebenzisa kakhulu idosi
Kuyahenda ukongeza isizinziso esongezelelekileyo “ukuze ukhuseleke,” kodwa oku kumosha imali kwaye kunokwenza ukuba iitarps ziqine. Sebenza nomthengisi wakho ukuvavanya ubuncinci bedosi esebenzayo: qala kwi-1% ye-Ca-Zn, i-1.5% ye-Ba-Zn, kwaye ulungelelanise ngokusekelwe kubushushu bakho bemveliso kunye nobukhulu betarp. Umzi-mveliso we-tarp waseMexico unciphise iindleko zokuzinzisa nge-15% ngokulula ngokunciphisa idosi ukusuka kwi-2.5% ukuya kwi-1.8%-ngaphandle kokuhla komgangatho.
2,Dibanisa kunye nezongezo zeSekondari
Izinzisi zisebenza ngcono nge-backup. Kwiitarps zangaphandle, yongeza i-2-3% yeoli ye-soy epoxidized (ESBO) ukunyusa ukuguquguquka kunye nokumelana nokubanda. Ukusetyenziswa kwe-UV-enzima, xuba kwixabiso elincinci le-antioxidant (njenge-BHT) ukuvimba umonakalo omkhulu wamahhala. Ezi zongezo zixabiso eliphantsi kwaye ziphinda-phinda ukusebenza kwesizinzisi sakho
3,Uvavanyo lweMozulu Yakho
Itarp ethengiswa eFlorida idinga ukhuseleko lwe-UV olungaphezulu kunokuthengiswa eWashington state. Qhuba iimvavanyo zebhetshi ezincinci: bonisa iisampulu zeetarp ekufaniseni ukukhanya kwe-UV (usebenzisa i-weatherometer) iiyure ezili-1,000, okanye uzifake emkhenkceni ngobusuku kwaye ujonge ukuqhekeka. Oku kuqinisekisa ukuba umxube wakho wokuzinzisa uhambelana nemarike ekujoliswe kuyo'iimeko s.
Izizinzi zichaza iTap yakho's ixabiso
Ekupheleni kosuku, abathengi bakho abakhathali ukuba usebenzisa ntoni na ukuzinzisa-bakhathalele ukuba i-tarp yabo ihlala kwimvula, ilanga kunye nekhephu. Ukukhetha isizinzi sePVC esifanelekileyo asiyondleko; yindlela yokwakha igama lemveliso ethembekileyo. Nokuba wenza ibhajethi yeetarps zezolimo (uncamathele ne-Ca-Zn) okanye i-premium industry covers (iya kwi-Ba-Zn okanye umhlaba onqabileyo), isitshixo kukutshatisa isizinzi nenjongo yetarp yakho.
Ukuba awuqinisekanga ukuba ngowuphi umxube osebenza kumgca wakho, cela umboneleli wakho wokuzinzisa ngeebhetshi zeesampulu. Zivavanye kwinkqubo yakho yemveliso, zibonise iimeko zehlabathi lokwenyani, kwaye uvumele iziphumo zikukhokele.
