MaResins ePVC ePremium SG3, SG5, SG7: Uinjiniya Hwakagadzirirwa Mhinduro dzeMaindasitiri Ekupedzisira kusvika Kumagumo

Kugadzirwa kweMolekyuru & Hunhu Hwemuviri

SG3 (Giredhi reKuchinjika Kwakakwirira)
Yakagadzirwa ne polymerization degree ye1300 - 1500 uye K - kukosha kwe70 - 72, giredhi iri rine mamorekuru marefu anosimudzira plasticizer ekubata. Kupararira kwayo kwe60 - 250μm kunoita kuti ipararire zvakaenzana mumafomura akapfava, zvichibvumira 25 - 35g ye plasticizer yekutora 100g resin. Chimiro chisina chimiro chinobuda chinopa kureba kwakanaka panguva yekupwanyika, zvichiita kuti ive yakakodzera zvigadzirwa zvinoda kuchinjika kakawanda pasina kutsemuka.

SG5 (Yakasiyana-siyana - Giredhi Yepakati)
Kuenzanisa mwero wepolymerization we1000 - 1100 neK - kukosha kwe65 - 67, SG5 inopa nzvimbo yepakati inochinja-chinja. Kuwanda kwayo kwezvikamu (0.45 - 0.58g/mL) kunoita kuti mvura inyungudike zvakanaka mu extrusion uye injection molding, ukuwo kunyungudika kwepurasitiki (20 - 28g/100g) kuchibvumira kuchinja kubva pa semi-rigid cable sheaths kuenda kuma low-flexible profiles. Kugara kwenguva refu kwemolecular chain kunoderedza zvikanganiso zvekugadzirisa, zvichiita kuti pave nekukora kwakafanana kwemadziro mu extrusion yepombi.

SG7 (Giredhi reUinjiniya Rakasimba)
Nechiyero chekupomera che700 - 850 uye K - kukosha kwe60 - 62, SG7 inotarisa kushanda zvakanaka kwepakeji yemamorekuru kuti irambe yakasimba. Chimiro chayo chezvikamu 40 - 180μm (density 0.50 - 0.62g/mL) chinoderedza maburi muzvikamu zvakaumbwa, zvichiwedzera kuramba kukanganiswa muprofiles dzekuvaka. Kunyudzwa kwepurasitiki kushoma (15 - 22g/100g) kunobvumira maformula akasimba zvakakwana, nepo residual vinyl monomer ≤3μg/g ichisangana nezvinodiwa zvekuchengetedza chikafu pakushandisa pakurongedza.

Maitiro Ekushandisa

SG3: Nyanzvi yeKuchinjika
Muzvikamu zvekurima, mafirimu eSG3 ane 40 - 50 phr plasticizer anoumbwa neUV - stabilized greenhouse covers, achienzanisa mwenje nekudzivirira misodzi. Pakushandisa kwekurapa, monomer yayo shoma inogonesa machubhu akapfava emuchina we dialysis, nepo mushangu, inogadzira soles dzinoramba dzakasimba dzinochengetedza chimiro pakuchinja-chinja kwekushisa.

SG5: Bhiza Rinoshanda Mumaindasitiri
Vagadziri vetambo vanoshandisa mhando dzepurasitiki dzeSG5 dze10 - 20 phr kugadzira masheya ekudzivirira moto anodzivirira moto emagetsi, zvichibatanidza kudzivirira kwemagetsi nekugara kwenguva refu kwemuchina. Pakuvaka, inobuda muzvidimbu zvekuvhara mahwindo zvisingapindi mamiriro ekunze, uko kuoma kwayo kuri pakati nepakati kunodzivirira kuora kwe ozone. Zvikamu zvemotokari zvakagadzirwa nejekiseni, zvakaita semagonhi, zvinobatsirwa nehuwandu hwazvo hwekusimba nehuremu.

SG7: Mutsigiri weKusimba
Masisitimu emapaipi emaindasitiri anoshandisa SG7's high modulus pakugadzira mapaipi etsvina asingapindi mishonga uye mapaipi emvura ane simba rekumanikidzwa. Mahwindo akaburitswa, kana akasanganiswa netitanium dioxide, anoratidza ruvara rwakasimba munzvimbo dzekunze. Vagadziri vemagetsi vanoishandisa pakuisa majekiseni emidziyo yakagadzirwa, vachishandisa kugadzikana kwayo panguva yekuisa tembiricha yakakwira.

Gwaro Rekugadzirisa Maitiro

Mafungiro eKutarisira Kupisa
SG3 inoda kudzora tembiricha zvakanyanya (160 - 180°C) kudzivirira kuora kwechinhu nguva isati yakwana; kunyangwe kupfumbuka kwakanyanya kwe10°C kunogona kukonzera kuburitswa kwehydrochloric acid, zvichikonzera kutsvuka kweyero. Kusiyana neizvi, SG7 inotsungirira kugadziriswa kwe180 - 200°C, zvichibvumira kukurumidza kubuda kwemvura mumapombi makuru, kunyangwe kupfuura 210°C kunogona kukonzera kupwanyika kwemasero emuchadenga.

Dhizaini yeSisitimu yekuwedzera
Kugadzikana: SG3 inoda 1 - 2 phr yecalcium - zinc composite stabilizers kuti idzivirire kuora kwekupisa panguva yekugadzirisa plasticizer yakawanda, nepo SG7 ichingoda 0.5 - 1 phr nekuda kwekuderera kwekushushikana kunokonzerwa neplasticizer.
Kuzora: Magiredhi ese anobatsirwa ne 0.2 - 0.5 phr ye polyethylene wax, asi SG3 ingangoda mazinga akawandisa ekuderedza kukweshana kwemukati mumakemikari akapfava.
Zvinowedzerwa Pakushanda: Maantioxidant ari muSG7 formulations anowedzera hupenyu hwekushanda panze, nepo ma impact modifiers ari muSG5 anowedzera kusimba kwe notch kune mashandisirwo echando kana mamiriro ekunze atonhora.

Hunyanzvi hweUinjiniya muKugadzira Resin

Nekubatanidza mainjiniya chaiwo e-molecular pamwe nekuyedzwa kunotungamirirwa nekushandiswa, portfolio yedu yeSG3, SG5, SG7 inopa simba vagadziri kuti vapfuure miganho yePVC yechinyakare. Kubva pakuchinjika kunodiwa kune zvinoraswa zvekurapa kusvika pakusimba kwechimiro kunodiwa nekuvakwa kwakakwirira, maresini aya anomiririra kusanganiswa kwesimba resainzi uye kushanda kwemaindasitiri—kuisa zviyero zvitsva zvemhinduro dzepolymer dzinotungamirirwa nekushanda.
