Zolepheretsa kuwala kwa amine sizimayatsa kuwala kwa UV monga momwe zoyatsira UV zimachitira - m'malo mwake, zimawononga ma free radicals opangidwa ndi kuwala kwa UV ndi kutentha, zomwe zimasokoneza kuwonongeka komwe kumayambitsa ming'alu, choko, kusinthika ndi kutayika kwa mphamvu zamakina mu mapulasitiki, zokutira, ulusi ndi zomatira. Kwa ogula omwe ali ndi udindo wopanga-nthawi yayitali ya malonda akunja, kusankha kwa HALS nthawi zambiri kumakhala kusiyana pakati pa kulephera kwazaka zisanu-ndi zaka makumi awiri{4}}zaka zautumiki. Ilinso limodzi mwazowonjezera zomwe zimafunikira mwaukadaulo kuti zipezeke moyenera, chifukwa{6}}mamolekyu otsika-kulemera kwa -mamolekyu-olemera kwambiri a HALS amachita mosiyana kwambiri malinga ndi ntchito.
Pain Point 1: Kusankha pakati pa otsika, apakatikati ndi apamwamba molekyulu yolemetsa HALS
Ogula atsopano ku HALS sourcing nthawi zambiri amadabwa ndi kuchuluka kwa kulemera kwa maselo. Otsika{{1}mamolekyu-olemera kwambiri a HALS nthawi zambiri amakhala okhazikika pa-gilamu imodzi ndipo amabalalika msanga, koma amakonda kusamuka komanso kusasunthika, zomwe zimapangitsa kuti zisagwirizane ndi mafilimu oonda kapena kusintha{4}}kutentha kwambiri. Okwera{{6}mamolekyu-olemera kwambiri a HALS ndi ma polymeric HALS amakana kusamuka ndi kuchotsedwa bwino kwambiri, zomwe zimafunikira pazinthu zomwe zimachapitsidwa, kuzizira, kapena kukhudzana ndi zosungunulira, ngakhale zitha kuwononga ndalama zambiri komanso zimafunika kusinthidwa mosiyanasiyana.
Kanema wocheperako waulimi kapena wazolongedza - amakonda kutsika-kusamuka, kutsika{2}}magiredi osasunthika omwe amapitilira{3}}kumeta ubweya wambiri
Zovala zokhala ndi nyengo komanso kuyeretsedwa kwa mankhwala - zimakonda kulemera kwa ma molekyulu kapena ma HALS omwe amalumikizana ndi filimuyi
Rotomolded kapena wandiweyani-zigawo - kubalalitsidwa ndi kukhazikika kwa kutentha munthawi yayitali ndizofunikira kwambiri kuposa kuthamanga kwa mayamwidwe
Zogulitsa zomwe zili ndi acidic (monga zoletsa malawi kapena ma acidic pigments) - zofunikira za HALS zimakhala zovuta kuti zigwirizane, osati kungochita
Pain Point 2: Mikangano yoyambira ndi "poizoni wa HALS"
Limodzi mwamavuto omwe ogula amakhumudwitsidwa nawo ndi HALS yomwe imachita bwino paokha koma osagwira bwino ntchito kamodzi akaphatikizidwa ndi zowonjezera zina za acidic - zoletsa ma halogenated flame retardants, ma pigment, kapena zotsalira za acidic kuchokera ku catalysts - chodabwitsa chomwe chimatchedwa kuti HALS poisoning, kumene ma neutralized 2 ndi ascacal sites} kusokonezedwa. Wopereka katundu yemwe amamvetsetsa momwe wogula amapangira, osati ma HALS okhawokha, atha kuyika chiwopsezochi chisanachitike kulephera kokwera mtengo kusanachitike.
Zomwe wopereka HALS wokhoza mwaukadaulo akuyenera kukambirana nanu:
Kaya phukusi lanu lamoto lomwe lilipo kale, pigment kapena filler likugwirizana ndi HALS Basicity.
Kaya giredi ya NOR-HALS ndiyabwino kwambiri pamakina okhala ndi acidic sulfure-rabara yochiritsa kapena zokutira zina
Mulingo wovomerezeka wa polima wanu, makulidwe a khoma ndi malo omwe akuyembekezeka
Kaya kulumikizana ndi cholumikizira cha UV kumakulitsa moyo wautumiki motsutsana ndi HALS yokha
Pain Point 3: Zolemba zowongolera ndi kutumiza kunja
Ogula omwe amatumiza katundu womalizidwa ku EU, US kapena misika ina yolamulidwa nthawi zambiri amafunsidwa ndi makasitomala awo kuti alembetse REACH, mapepala achitetezo, ndi chizindikiritso cha CAS chosasinthika - ndipo mochulukirachulukira, umboni woti phukusi lowonjezera siliyambitsa zinthu zoletsedwa. Wopereka HALS yemwe sangathe kutembenuza zolembedwazi amachepetsa kugulitsa kwa wogulayo, ndichifukwa chake kuthamanga kwa zolemba kwakhala kofunikira kwa ogula ambiri monga mtengo.
Pain Point 4: Kupanga mwamakonda ndi chimodzi-chothandizira kuwala koyimitsa-kukhazikika
Ogula ambiri safuna kuyang'anira othandizira awiri kapena atatu osiyana ndikuthetsa momwe zinthu zawo zimagwirira ntchito. Pakuchulukirachulukira gwero limodzi lomwe lingathe kupereka chowumitsira UV choyezedwa kuphatikizanso HALS system - nthawi zina ngakhale ngati -zosakaniza zosakaniza - zokonzedwa ndi utomoni winawake ndi ntchito, m'malo mosiya wogula kuti aphatikize{4}}zigawo ziwiri zokha moyesera.
Umu ndi momwe machitidwe aukadaulo a Diheng amapangidwira: chifukwa kampaniyo imapanga zotsekemera zonse za UV ndikulepheretsa zowongolera za amine, ndipo imagwira ntchito pamapulasitiki, zokutira, mafilimu, ma elastomers, nsalu ndi zomatira, imatha kupangira makina ophatikizika ogwirizana ndi utomoni wa wogula, njira yopangira ndi moyo wamakasitomala, m'malo mongopereka makina amodzi okha.
The Practical Takeaway
HALS sourcing imapatsa mphotho ogula omwe amapitilira nambala imodzi ya data ndikufunsa za kulemera kwa mamolekyulu, kugwirizana koyenera ndi zina zonse zomwe zalembedwa, ndikusintha zolemba musanapereke kwa ogulitsa. Wopanga amene angathe kuthandizira - chemistry kusankha, machitidwe{2}}upangiri wa mlingo, ndi kaphatikizidwe kosasintha - amachepetsa chiwopsezo cha wogula kuposa momwe mtengo wa unit ungathere wotsikirapo.
