Ncamathisela iCalcium Zinc PVC Stabilizer: I-PVC engcono, iMveliso ehlakaniphile

Njengesongezo sokusika se-polyvinyl chloride (PVC) processing,Ncamathisela iCalcium Zinc (Ca-Zn) iPVC Stabilizeriye yavela njengenye indlela ekhethwayo kunezinye izizinzisi ezisekelwe kwisinyithi esinzima (umzekelo, ilothe, i-cadmium). Indibaniselwano yayo eyodwa yokhuseleko, ukusebenza, kunye nokuthotyelwa kokusingqongileyo kujongana neemfuno ezibalulekileyo kuwo onke amacandelo emveliso yePVC enemfuno ephezulu. Apha ngezantsi kucazululwe ngeenkcukacha zezibonelelo zayo ezingundoqo, ububanzi besicelo esandisiweyo, kunye nendlela esombulula ngayo iindawo ezibuhlungu ezihlala ixesha elide kwimveliso yePVC.

1. Izinto eziluncedo ezingundoqo: uKhuseleko, ukuSebenza, kunye nokuThotyelwa​

Ncamathelisa uCa-ZnIsizinzi sePVCibalasele ekusebenzeni kwayo okunemigangatho emininzi, iyenza ilungele ukusetyenzwa kwePVC ngokubanzi kunye nokucaciswa okuphezulu.

1.1 Ukuthotyelwa kweNkangala yetyhefu kunye ne-Eco-Friendly

Ikhululekile kwiintsimbi ezinzima eziyingozi (ilothe, i-cadmium, imekyuri, njl. njl.), ihlangabezana ngokupheleleyo nemigaqo yokusingqongileyo nokhuseleko lwehlabathi, kuquka i-EU's REACH Regulation, i-RoHS Directive, kunye ne-US CPSIA (uMthetho wokuPhuculwa koKhuseleko lweMveliso yoMthengi). Oku kuphelisa imingcipheko yempilo kubasebenzi bemveliso kunye nabasebenzisi bokugqibela, ngelixa uthintela izohlwayo ezilawulayo kubavelisi abathumela ngaphandle kwiimarike zamazwe ngamazwe.

1.2 UkuNgafihli okuBalaseleyo kunye noMgangatho woBubuhle

Ngokungafaniyo nezinye izizinzi ezenza iPVC ibetyheli okanye ilifu, Cola iCa-Zn PVC Stabilizer igcina ukucaca kwendalo. Igcina ukuhanjiswa kokukhanya okuphezulu nakwiimveliso zePVC ezinodonga olucekethekileyo okanye ezinemibala, imfuno ephambili yosetyenziso apho isibheno esibonakalayo (umzekelo, izinto zokudlala ezicacileyo, iityhubhu yezonyango) okanye ukusebenza kwemveliso (umzekelo, imibhobho ecacileyo yokubonwa kolwelo) ibalulekile.

1.3 Uzinzo oluPhezulu lweDynamic kunye nokuChasa ukuguga

I-PVC ithanda ukuthotywa kwe-thermal ngexesha lokucubungula (umzekelo, i-extrusion, i-calendering) kunye nokuguga kwe-oxidative ngexesha lokusetyenziswa kwexesha elide. Esi sinzisi senza ifilimu ekhuselayo kwimixokelelwane ye-PVC yeemolekyuli, ixhathise ngokufanelekileyo ukubola okubangelwa ukushisa (nangona kwi-160-180 ° C yokushisa ukushisa) kunye nokunciphisa i-UV / i-oxidation-related brittleness. Uvavanyo lwangaphandle lubonisa iimveliso ezenziwe ngayo zine-30-50% yobomi benkonzo obude xa kuthelekiswa nezo zisebenzisa iziqinisekiso eziqhelekileyo.

1.4 Ukusebenza okugqwesileyo kunye nevumba eliphantsi

Ngokuhambelana kakuhle kunye ne-PVC resins kunye neplastiki, i-Paste Ca-Zn PVC Stabilizer iqinisekisa ukusabalalisa okufanayo ngexesha lokuxuba-ukunciphisa imiba yokuvelisa njenge-agglomeration yezinto okanye ukunyibilika okungalinganiyo. Ikwanciphisa ukukhutshwa kweekhompawundi ze-organic (VOCs), okukhokelela kwiimveliso ezikufutshane-ezingenavumba. Lo ngumdlalo wokutshintsha usetyenziso lwendawo evalelweyo (umzekelo, izicoci zefriji) kunye namacandelo anovakalelo (umzekelo, izixhobo zonyango).

2. UMda weSicelo owandisiweyo​

Ukuguquguquka kwayo kwenza iCostaCa-Zn PVC ukuzinzisailungele ukubonakala okuphezulu, ukhuseleko-olubalulekileyo, kunye neemveliso zePVC ezingevani nevumba, ezibandakanya abathengi kunye namacandelo oshishino:

2.1 I-High-Transparency PVC Soft & Semi-Rigid Products

• Ukusetyenziswa kweKhaya kunye neMihla:Izicoci zefriji ezicacileyo (ezikwazi ukumelana nobushushu obubandayo kunye noqhagamshelwano lokutya), iiglavu zevinyl ezicacileyo (inqanaba lezonyango okanye lokutya, elingenatyhefu), kunye nezinto zokudlala zePVC eziguquguqukayo (ezihambelana ne-EN 71 kunye nemigangatho yokhuseleko ye-ASTM F963 yabantwana).

• Umzi-mveliso & Usetyenziso:Imibhobho yePVC ecacileyo (yamanzi, umoya, okanye ukuhanjiswa kweekhemikhali, apho ukubonakala kolwelo kuthintela ukuvaleka) kunye namaphepha ePVC aqinileyo (asetyenziswa kwiimeko zokubonisa okanye ukupakishwa kombane).

2.2 IiMveliso zePVC zoNyango (Ezikumgangatho oPhezulu, azinavumba).

I-PVC yonyango ifuna ukuthotyelwa ngokungqongqo kwi-biocompatibility kunye nobunyumba. Lo uzinzisi udibana ne-ISO 10993 (uvavanyo lwebhayoloji yezixhobo zonyango) kunye nemigangatho ye-USP yoHlelo lwe-VI, iyenza ilungele:

• Izixhobo zokuphefumla:Iimaski zeoksijini kunye neetyhubhu ze-nebulizer (ivumba eliphantsi liqinisekisa intuthuzelo yesigulana ngexesha lokusetyenziswa kwexesha elide).

• Ulawulo lolwelo:I-Intravenous (IV) iityhubhu zokuthontsiza, iibhegi zegazi (ezikwaziyo ukumelana nemichiza ngegazi okanye amayeza), kunye neecatheters.

• Izixhobo zokutofa:Imiphanda yesirinji kunye namalungu enaliti yezonyango (ayiyotyhefu, eqinisekisa ukuba akukho kukhutshwa kwezinto ezinobungozi kulwelo lomzimba).

2.3 Ukutya-Qhagamshelana neeMveliso zePVC

Ngaphandle kokusetyenziswa kwezonyango, ikwavunyiwe kwizicelo zoqhakamshelwano lokutya (umzekelo, iifilimu zePVC ezingafihliyo zokupakishwa kokutya, amabhanti okuhambisa kwizityalo zokuhambisa ukutya), njengoko ihambelana ne-FDA 21 CFR iSigaba 177.1520 (i-PVC resins zoqhagamshelwano lokutya).

3. Ukusombulula iiNgxaki eziPhambili kwiMveliso yePVC

Abavelisi bePVC bahlala bejongana nemingeni enxulumene nokhuseleko, ukusebenza, kunye nokuthotyelwa-imiba ethi Paste Ca-Zn PVC Stabilizer isombulula ngokuthe ngqo:

3.1 Ukuphelisa iiNgozi eziNxibelelayo eziNcedayo

Izizinzisi ezisekelwe kwilothe ngokwesithethe zibeka imingcipheko yokuba sesichengeni sabasebenzi (ngothuli okanye umsi) kunye nokungcoliseka kwemveliso (umzekelo, ukuvuza kwelothe kwizinto zokudlala okanye ukupakishwa kokutya). Le fomula yentsimbi engenazinzisi isusa ezi ngozi, inqanda ukukhunjuzwa kwemveliso kunye nokukhusela isidima sohlobo.

3.2 Ukoyisa iLahleko yokungafihli kwiNkqubo

Uninzi lwezinzisi zisabela ngePVC's plasticizers okanye iiresin, ezibangela ukujika kombala okanye amafu. Ncamathelisa ukusebenza okuphantsi kwe-Ca-Zn PVC Stabilizer igcina ukucaca, inciphisa amaxabiso ezinto ezilahliweyo ezibonisa elubala izinto eziphezulu (umzekelo, i-10–15% ezimbalwa zeeyunithi ezineziphene kwizinto zokudlala okanye kwimveliso yetyhubhu yezonyango).

3.3 Ukuthintela ukuthotywa kweThermal ngexesha lokuLungiswa kobushushu obuphezulu

I-PVC ibola kumaqondo obushushu aphezulu, ikhupha i-hydrochloric acid (HCl) kwaye ibangele ukubola kwempahla okanye ukubola. Ukumelana nobushushu okuqinileyo kolu kuzinziswa kugcina uzinzo lwePVC ngexesha lokukhupha okanye ukubumba, ukuqinisekisa umgangatho wemveliso ongaguqukiyo kunye nokunciphisa ixesha lokuphumla kwi-corrosion yezixhobo (ezibangelwa yiHCl).

3.4 IiMfuno zeNtlanganiso yevumba kunye ne-Biocompatibility kuMacandelo abuthathaka

Iimveliso zonyango kunye nezekhaya zePVC zihlala zisilela kwisiqinisekiso ngenxa yevumba elishiyekileyo okanye izinto ezivuzayo eziyityhefu. Ukukhutshwa kwe-VOC ye-stabilizer ephantsi kunye nokwakheka okungeyotyhefu kuqinisekisa ukuthotyelwa kweemvavanyo ze-biocompatibility yezonyango kunye nemigangatho yevumba lasekhaya, ukukhawulezisa ixesha lokuya kwintengiso yeemveliso ezintsha.

Ncamathelisa iCalcium Zinc PVC Stabilizer ivala umsantsa phakathi kokhuseleko, ukusebenza, kunye nokuthotyelwaabavelisi bePVC. Iprofayile yayo engeyiyo ityhefu, eco-friendly idibana nemithetho yehlabathi, ngelixa ukungafihli, uzinzo, kunye nokuqhubekeka kuphucula umgangatho wemveliso kubathengi, amashishini, kunye namacandelo ezonyango. Ngokusombulula imiceli mngeni engundoqo njengokungcoliseka kwentsimbi enzima, ilahleko elubala, kunye nokuthotywa kobushushu, iye yaba sisongezo esiyimfuneko kwizicelo zePVC zexabiso eliphezulu-ingakumbi ezo zifuna ukhuseleko olungqongqo okanye imigangatho yobuhle.
