Khawube nomfanekiso woku: Umgca we-extrusion womzi-mveliso wakho uya kunqumama kuba ifilim ye-PVC eshwabeneyo ihlala ijika ibemnkum phakathi komdlalo. Okanye umxhasi ubuyisela ibhetshi-isiqingatha sefilimu sinciphe ngokungalinganiyo, sishiya ukupakishwa kwemveliso kukhangeleka kumdaka. Ezi ayizongxaki nje ezingephi; ziingxaki ezixabisa imali eninzi ezimiliselwe kwicandelo elinye elisoloko lingahoywa: yakhoPVC ukuzinzisa.
Nabani na osebenza nge-PVC ecuthayo ifilimu-ukusuka kubaphathi bemveliso ukuya kubayili bokupakisha-izinzisi azizo "zongezo". Zizilungiso zezona ndawo zixhaphakileyo zentlungu kushishino, ukusuka kumazinga aphezulu okulahlwa ukuya kubukho beshelufu yokunqongophala. Masiyicalule indlela abasebenza ngayo, yintoni ekufuneka siyiphephe, kwaye kutheni ukuzinzisa okufanelekileyo kunokuguqula abathengi abaphoxekileyo babe ngabathengi abaphindayo.
Okokuqala: Kutheni iFilimu yeShrink yahlukile (kwaye kunzima ukuzinza)
Ifilimu yokushwabana yePVC ayifani nefilimu yokuncamathela rhoqo okanye imibhobho engqongqo yePVC. Umsebenzi wayo kukuncipha xa ifunwa—ngokuqhelekileyo xa ibethwa bubushushu obuvela kwitonela okanye umpu—ngoxa ihlala yomelele ngokwaneleyo ukuze ikhusele iimveliso. Loo mfuneko imbini (ukusabela kobushushu + ukuqina) yenza uzinzo lube luqilima:
• Ukulungiswa kobushushu:Ukukhupha ifilimu yokushwabana ifuna amaqondo obushushu ukuya kuma 200°C. Ngaphandle kwezinzisi, i-PVC idiliza apha, ikhupha i-hydrochloric acid (HCl) eyonakalisa izixhobo kwaye iguqule ifilimu ibe tyheli.
• Ubushushu obucuthayo:Emva koko ifilimu kufuneka iphathe i-120-180 ° C kwakhona ngexesha lokufaka isicelo. Uzinzo oluncinane kakhulu, kwaye luyakrazula; kakhulu, kwaye ayiyi kuncipha ngokulinganayo.
• Beka ubomi kwishelufa:Xa sele ipakishiwe, ifilimu ihlala kwiindawo zokugcina iimpahla okanye phantsi kwezibane zevenkile. Imisebe ye-UV kunye neoksijini iya kwenza ifilimu engazinzanga ibe brittle kwiiveki-kungekhona iinyanga.
Iplanti yokupakisha ephakathi e-Ohio yafunda oku ngendlela enzima: Batshintshela kwi-lead-based stabilizer efikelelekayo ukunciphisa iindleko, ukubona kuphela amazinga e-scrap axhuma ukusuka kwi-5% ukuya kwi-18% (ifilimu igcinwe ukuqhekeka ngexesha lokukhupha) kunye nomthengisi omkhulu wala ukuthunyelwa ngenxa ye-yellowing. Ukulungiswa? Ai-calcium-zinc (Ca-Zn) i-stabilizer. Amaxabiso e-Scrap ahle abuyela kwi-4%, kwaye aphephe i-150,000 yeedola zemali yokucwangcisa kwakhona.
Amanqanaba ama-3 apho abaZinzisi benza okanye baphule ifilimu yakho ecuthekileyo
Izinzisi azisebenzi nje kube kanye-zikhusela ifilim yakho kwinyathelo ngalinye, ukusuka kumgca wokukhupha ukuya kwishelufu yevenkile. Nantsi indlela:
1.Inqanaba leMveliso: Gcina iMizila eSebenzayo (kwaye unciphise iNkunkuma)
Elona xabiso likhulu kwimveliso yefilim ecuthayo lixesha lokuphumla. Izizinzi ezinezithambiso ezakhelwe ngaphakathi zinciphisa ukungqubana phakathi kwe-PVC yokunyibilika kunye ne-extrusion iyafa, ikhusela "i-gelling" (i-resin e-clumpy evala oomatshini).
•Ukucutha ixesha lokutshintsha ngama-20% (ukucocwa okuncinci kokudubula kuyafa)
•Ukunciphisa amazinga e-scrap-i-stabilizers ezilungileyo ziqinisekisa ubukhulu obuhambelanayo, ngoko awuyi kulahla imiqulu engalinganiyo.
•Yandisa isantya somgca: Ukusebenza okuphezuluCa-Znimixube vumela imigca iqhube 10–15% ngokukhawuleza ngaphandle kokuncama umgangatho
2.Inqanaba leSicelo: Qinisekisa nokuba uyashwabana (akusekho ukuPakisha okuneqhuma)
Akukho nto ibakhathazayo abanini bebhrendi njengefilimu eshwabeneyo ejinga kwindawo enye okanye itsale iqine kakhulu kwenye. Izizinzi zilawula indlela iimolekyuli zePVC eziphumla ngayo ngexesha lokufudumeza, ziqinisekisa:
•Ukuncipha okufanayo (50-70% kwicala lomatshini, ngokwemigangatho yeshishini)
•Akukho "necking" (amabala amancinci akrazula xa usonga izinto ezinkulu)
•Ukuhambelana nemithombo eyahlukeneyo yobushushu (iitonela zomoya oshushu vs. imipu ephathwa ngesandla)
3.Inqanaba lokuGcina: Gcina ifilimu ijongeka iNtsha (inde)
Nokuba eyona filimu incinci incinci iyasilela ukuba iguga kakubi. I-UV stabilizers isebenza kunye ne-thermal stabilizers ukuvala ukukhanya okuphula i-PVC, ngelixa i-antioxidants icotha i-oxidation. Isiphumo?
•I-30% yobomi obude beshelufu kwiifilimu ezigcinwe kufutshane neefestile okanye kwiindawo zokugcina iimpahla ezifudumeleyo
•Akukho tyheli-ibalulekile kwiimveliso zeprimiyamu (cinga izithambiso okanye ibhiya yobugcisa)
•Ukubambelela okungaguqukiyo: Ifilim ezinzileyo ayizukulahlekelwa "yibambe nkqi" kwiimveliso ngokuhamba kwexesha
Ii-Big Mistake Brands Yenza: Ukukhetha izizinzisi kwiindleko, hayi ukuthotyelwa
Imimiselo ayingomgca obomvu kuphela-ayiyokuxoxisana ngokufikelela kwimarike. Nangona kunjalo abavelisi abaninzi basakhetha izizinzisi ezingabizi kakhulu, ezingathobeliyo, kuphela ukujongana nokukhatywa okunexabiso elikhulu:
• I-EU FIKELELA:Ukususela ngo-2025, i-lead kunye ne-cadmium kwi-PVC yokupakisha ivaliwe (akukho manqanaba abonakalayo avunyelweyo).
• Imithetho ye-FDA:Kwiifilimu ezijongene nokutya (umzekelo, iibhotile zamanzi ezisongayo), izizinzi kufuneka zihlangane ne-21 CFR Icandelo le-177-ukufudukela ekutyeni akunakudlula i-0.1 mg / kg. Ukusebenzisa izinzisi zodidi lwemizi-mveliso apha kubeka emngciphekweni izohlwayo ze-FDA.
• eTshayina's Imigangatho emitsha:ISicwangciso seMinyaka emiHlanu se-14 sigunyazisa ukuba i-90% yezinzinzisi eziyityhefu zithatyathelwe indawo ngowama-2025.
Isicombululo? Yeka ukujonga izizinzi njengeziko leendleko.Izinzisi zeCa-Zninokubiza i-10-15% ngaphezu kweenketho ezisekelwe kwi-lead, kodwa ziphelisa iingozi zokuthobela kunye nokunciphisa inkunkuma-ukugcina imali kwixesha elide.
Indlela yokukhetha isizinzisi esiLungileyo
Awudingi isidanga sekhemistri ukuze ukhethe ukuzinzisa. Phendula nje le mibuzo mi-4:
▼ Intoni's imveliso yokugqibela?
• Ukupakishwa kokutya:I-FDA-ithobela i-Ca-Zn
• Iimveliso zangaphandle (umzekelo, izixhobo zasegadini):Yongeza i-UV stabilizer
• Ukusonga umsebenzi onzima (umz., iipalethi):Imixube ephezulu yomatshini-amandla
▼ Ukhawuleza kangakanani umgca wakho?
• Imigca ecothayo (ngaphantsi kwe-100 m/min):Isiseko seCa-Zn siyasebenza
• Imigca ekhawulezayo (150+ m/min):Khetha izizinzi kunye ne-lubrication eyongezelelweyo ukuthintela ukukhuhlana.
▼ Ngaba uyayisebenzisa iPVC esetyenzisiweyo?
• I-Post-consumer resin (PCR) idinga i-stabilizers kunye nokumelana okuphezulu kwe-thermal-jonga iilebula "ezihambelana ne-PCR".
▼ Intoni's injongo yakho uzinzo?
• Izizinzisi zeBio-based (ezenziwe ngeoyile yeembotyi zesoya okanye irosin) zinemizila yekhabhoni esezantsi ngama-30% kwaye zisebenza kakuhle kwii-eco-brands.
Izinzisi ziyiMfihlo yakho yoLawulo loMgangatho
Ekupheleni kosuku, ifilimu ye-shrink ilungile kuphela njenge-stabilizer yayo. Indlela enexabiso eliphantsi, engahambelaniyo inokonga imali ngaphambili, kodwa iya kukubiza ngelahleko, ukuthunyelwa kwempahla, kunye nokulahlekelwa yithemba. I-stabilizer efanelekileyo-ngokuqhelekileyo i-Ca-Zn blend elungiselelwe iimfuno zakho-igcina imigca isebenza, iipakethi zibukeka zibukhali, kunye nabaxhasi bonwabile.
Ukuba ujongene namazinga aphezulu okulahlwa, ukucutheka okungalinganiyo, okanye ukukhathazeka kokuthotyelwa, qala ngokuzinzisa kwakho. Idla ngokuba sisilungiso osilelayo.
