Cov khoom siv sab nraum zoov- suav nrog cov chaw them nyiaj EV, cov khoom siv hluav taws xob, cov khoom siv ua liaj ua teb, thiab cov khoom siv sab nraum zoov- txhua tus ntsib ib qho kev sib tw: raug tshav ntuj, nag, kub hloov pauv, thiab kev laus. Yog tias cov yas tsis raug xaiv, qhov tshwm sim muaj xws li yellowing me ntsis thiab brittleness mus rau hnyav tawg thiab tag nrho cov khoom tsis ua hauj lwm.
Tsab ntawv xov xwm no yog lub hom phiaj los pab koj kom paub meej: Thaum tsim cov khoom siv sab nraum zoov ntawm lub tshuab nqus tsev, cov yas twg muaj qhov ua tau zoo tshaj plaws thiab muaj zog?
Kev sib piv ntawm tsib feem ntau siv sab nraum zoov yas

3. PMMA (Acrylic)- Xaiv Qhov no kom pom tseeb
Huab cua Resistance: ⭐⭐⭐
Nta:
Lub teeb xa tawm ntawm 92%-txawm tias pom tseeb dua iav.
Zoo heev huab cua tsis kam; tsis daj sab nraum zoov (zoo tshaj rau PC).
High deg hardness; resistant rau khawb.
Tus nqi nruab nrab.
Qhov tsis zoo:
Txhaws; tsis tshua muaj kev cuam tshuam lub zog-nruj tawg yog tias poob.
Qhov nruab nrab kub tsis kam (70-80 degree).
Haum rau:
Pob tshab npog rau ntsuas vaj huam sib luag.
Saib qhov rais thiab qhov chaw saib.
Lightbox panels.
Cheebtsam xav tau pob tshab tab sis tsis muaj kev cuam tshuam siab.
Hauv Cov ntsiab lus: PMMA yog qhov kev xaiv saum toj kawg nkaus rau cov khoom pob tshab-tsuas yog ceev faj tsis txhob tso lawv.
4. HDPE(High-Density Polyethylene) - Nqis, Durable, thiab Dej-Resistant
Huab cua Resistance: ⭐⭐⭐
Nta:
Qhov kev xaiv pheej yig tshaj plaws.
Cov tshuaj tiv thaiv zoo heev (tsis cuam tshuam los ntawm acids, bases, los yog ntsev tsuag).
Tsis yog-absorbent; muab zoo heev waterproofing.
Yooj yim; resistant rau tawg raws li kev cuam tshuam.
Disadvantages: Tsis zoo UV tsis kam; yuav tsum tau ntxiv cov carbon dub los yog UV stabilizers rau sab nraum zoov siv.
Tsawg rigidity; kuj mos thiab yooj yim rau deformation.
Yooj yim rau xim los yog daim ntawv cog lus zoo.
Haum rau:
Cov khoom siv ua liaj ua teb (pub troughs, waterers).

3 Cov Ntsiab Lus Tseem Ceeb rau Cov Plastics Sab Nraud
1. Tsis txhob siv ABS ncaj qha rau sab nraum zoov
ABS muaj huab cua tsis zoo; thaum raug sab nraum zoov, nws pib daj thiab ua nkig nyob rau hauv tsuas yog 3 mus rau 6 lub hlis. Yog tias tus neeg siv khoom hais rau lub tsev dawb, nws yog qhov tsim nyog yuav tsum siv ASA lossis PC nrog UV- txheej tiv thaiv.
2. UV Stabilizers Tsis yog Panacea
Thaum qhov sib ntxiv ntawm UV stabilizers tuaj yeem txuas ntxiv lub neej kev pab cuam ntawm yas los ntawm ob mus rau peb zaug, nws tsis ua rau cov khoom siv mus tas li indestructible. Nyob rau hauv ib puag ncig uas raug UV hnyav heev - xws li siab - thaj chaw siab lossis suab puam - kev siv ASA tseem ceeb heev.
3. Xim kuj cuam tshuam rau huab cua tsis kam
Dub thiab Tsaus Xim: Cov no nqus cua sov ntau, yog li ua rau muaj kev pheej hmoo ntawm thermal aging; Txawm li cas los xij, lawv muaj peev xwm ua tau zoo dua UV tsis kam (raws li cov pa roj carbon dub ua raws li lub ntuj UV absorber).
Dawb thiab Teeb Xim: Cov no muaj kev cuam tshuam UV hluav taws xob; Txawm li cas los xij, cov resin nws tus kheej yog qhov yooj yim dua rau yellowing, yuav tsum muaj lub zog ruaj khov dua.
