application

Raw material kuumbwa uye zvivakwa zvePVC huni plastiki.

PVC yemuti poda uye huni faibha uye inorganic kuzadza (calcium carbonate), lubricant, stabilizer, foaming agent, foaming regulator, toner uye zvimwe zvine chekuita nekuwedzera (plasticizer, toughening agent, coupling agent), nezvimwe.

1, resin yemumbaSG-7, SG-7 resin fluidity yakanakira kupupa, asiwo kuderedza mutengo wekusanganiswa SG-5 mhando.

2. Kuzadza kunonyanya kuve hupfu hwehuni (kazhinji inenge 80-120 mesh yehuni yehuni uye yakawanda poplar huni hupfu), uye calcium carbonate inowedzera chiedza calcium carbonate (800-1000-1200 mesh).

3, mafuta ekuzora anowanzo shandisa stearic acid, parafini, PE wax, calcium stearate uye mamwe masanganiswa zvichienderana nechikamu chinodiwa kuumba huni hwepurasitiki lubricant system.Stearic acid, parafini yakachipa yakanaka yekuzora kuita, kushata kwayo ndiyo yakaderera kunyungudika (kupfuura 50 madhigirii), yakaderera kunyungudika kwemafuta pakupa lubricity inewo mhedzisiro yeplasticizer, pesvedzero yakadaro kuoma kwezvigadzirwa, chigadzirwa d kadhi. uye thermal deformation tembiricha yakaderera zvigadzirwa pamwe netembiricha, zviri nyore deformation uye zviri nyore kunayisa zvinokanganisa kugadzirwa.Kana PE wakisi iri 100% yakachena, nzvimbo yekunyunguduka inogona kusvika kupfuura 100 madhigirii haizodzikisi vica yechigadzirwa, uye inogona kugadzira dhizaini yakanyanya kupisa tembiricha yefirimu pamusoro pechigadzirwa, kuitira kuti kupenya kwepamusoro chigadzirwa chacho chinonyanya kuoneka.Calcium stearate inogona kumhanyisa plasticization yezvinhu uye ine imwe kugadzikana mhedzisiro.

4, stabilizer, inoshandiswa pakugadzirwa kwePVC ye stabilizer compound lead salt stabilizer, organic tin, calcium zinc stabilizer, etc. The stabilizer inowanzoshandiswa mumapuranga epurasitiki muChina inoumbwa nemutungamiri wemunyu stabilizer, iyo ine zvakanakira mutengo wakachipa uye kugadzikana kwakanaka kwekupisa. .Kuipa kwacho kune chepfu uye kwete nharaunda.Nekudaro, chikamu cheanosanganiswa lead salt stabilizer lubricant chinenge 50%.Kugadzikana kwe calcium uye zinc heat stabilizer yakashata kupfuura ye lead salt stabilizer, asi ine hushamwari kwezvakatipoteredza uye isina chepfu.Kuti uvandudze mashandiro, calcium uye zinc stabilizer inowanzosanganiswa ne antioxidant uye yakanyanya tembiricha wax, stearic acid, nezvimwewo, iyo inogadzirwa kuita yakawanda-inoshanda, yakawanda-chinangwa uye yakakwirira-inoshanda PVC yekugadzirisa mubatsiri nenzira yakakosha.Inokodzera kugadzirwa kwezvakatipoteredza PVC zvigadzirwa uye yakakwirira-kuzadza zvigadzirwa.Iyo yakanakisa kupisa stabilizer uye kugadzirisa mubatsiri wehuni - zvigadzirwa zvepurasitiki.A:

1. Teerera mirairo yeEU ROHS uye PAHS mitemo;

2. Mune resin imwechete pasi pechigadziro chekuenzanisa organic tin uye lead salt stabilizer yakakodzera kuwedzera huwandu hwekuzadza.

3. Iyo yekutanga tinting midziyo yakafanana neye organic tin, organic tini ine kunhuhwirira kwakasiyana, calcium uye zinc stabilizer haina kunhuhwirira kwakasiyana.

4. Kugadziriswa kwekuita kuri nani pane organotin uye lead salt stabilizer, nekuti ndeye stearic acid sipo, inokurumidza kugadzirwa kwepurasitiki.

5. Kuwanda kwe calcium uye zinc stabilizer inofananidzwa nePVC resin, saka kupararira kwayo kuri nani kupfuura iyo ye organotin uye lead salt stabilizer, iyo inonyanya kubatsira pakupararira kwayo mu resin;

6. Inogona kuvandudza kupera kwepamusoro kwezvigadzirwa;

7. Kugadzikana kwakanaka kwekushisa uye kutanga kwemavara.

8. Wedzera zvishoma kudarika mutengo wakafanana unotungamira stabilizer

5, iyo inofuridza inowanzoshandiswa neAC inofuridza agent uye chena inofuridza agent.Zvakanakira zve AC foaming agent ihombe yebvudzi vhoriyamu, huwandu hwacho hudiki, chakashata ndechekuti kuora kusina kukwana kunoramba kuri chikamu chidiki muzvigadzirwa, mukushandiswa kwekushandisa kuchave kuoneka kusavapo kwechigadzirwa, furo mumiriri kune chigadzirwa nzvimbo uye kusavapo kunoitwa. zvigadzirwa zvinotsungirira-mamiriro ekunze zvinogona kukurumidzira kukwegura, kuburitsa huwandu hukuru hwekuora kwekushisa, kukonzera kuora kwezvigadzirwa kuchinja ruvara, chena is endothermic foaming agent uye foaming agent Kuwedzera kwakakodzera kunogona kudzikamisa kupisa kwakanyanya kunoburitswa nekuora kwe AC inofuridza agent, saka. kuti ruvara rwechigadzirwa rwakanyanya kuchena.

6, furo regulator rinowanzo kusarudzwa kaviri kirasi A yakakwira viscosity regulator, yakapetwa kirasi A regulator (senge HF-100/200/80, nezvimwewo) kwete chete kuramba mamiriro ekunze kuri pamusoro, asi zvakare ine yakanakisa kuita kweplasticizing kuita, ita chigadzirwa pamusoro. yakawanda compact, gloss iri nani.Kuwedzerwa kwefuro regulator kunogona kumhanyisa plasticization uye kuchengetedza mashandisiro esimba pane yakaderera tembiricha.Foaming regulator inogona kugadzirisa zvirinani kufana uye kuwanda kwemakomba efuro, zvinonyatso kuderedza kuwanda kwehuni epurasitiki foam zvigadzirwa.Iye zvino, kuitira kuderedza mari, vazhinji vanogadzira mapurasitiki emapuranga vanosarudza kushandisa zvinhu zvakawanda zviduku zvepombi, zvinhu zvepurasitiki zvakadai semarara ekugadzirwa kwemadziro, mutsara unotamba chigadziko, zvakadai sezvigadzirwa zvepurasitiki zvehuni, zvinhu zvechipiri zvepurasitiki zvinodzokera shure nekukurumidza kudarika zvitsva. zvinhu zvakawanda, zvine simba rakaderera kunyunguduka, kuitira kuti chigadzirwa chiite zvirinani, inogona kusarudza plasticizing inononoka kunyunguduka simba refoam regulator (senge HF - 80/901) mhedzisiro iri nani, Chokwadi, mutengo uchakwira kupfuura HF-100 series.

7, inokodzera ecological huni ruvara poda yero, tsvuku, dema, titanium dioxide zvichingodaro.Yero uye tsvuku colorants inorganic uye organic.Chakanakira inorganic toner ndechekuti iri nani pane organic toner mukupikisa kwemamiriro ekunze uye kuramba kutama uye kupisa kwakanyanya.Izvo zvisingabatsiri ndezvokuti huwandu hwe inorganic toner yakakura, iyo isingakodzeri mavara akajeka, asi mutengo unodhura.Organic toner pane zvinopesana.Ecological huni inowanzo shandiswa musanganiswa ne organic uye inorganic toner.Titanium dioxide ine rutile rudzi uye anatase rudzi rwechipiri.Rutile rudzi rwekuvhara simba uye kuramba mamiriro ekunze zviri nani pane anatase type, saka ecological huni kazhinji ine rutile titanium dioxide.

8, CPE, kazhinji inosarudza 135A mhando, parizvino inonyanya kudhura-inoshanda toughening modifier pamusika, kuwedzera kwakakodzera kunogona kugadzira zvigadzirwa zvepurasitiki zvehuni nekuoma kuri nani, asi huwandu hwezvigadzirwa zvakapfava mushure mekuwedzera, teerera kugadzirisa huwandu hwekushandisa. .

9. DOP uye epoxy soya mafuta anowanzo shandiswa PVC ecological huni plasticizer.DOP inogona kuderedza iyo intermolecular simba resin kuvandudza fluidity, uye ine imwe lubricity inobatsira mukugadzira uye kugadzirisa.Asi inogona kuderedza mutevedzeri wechigadzirwa.Imwe kilogiramu yeDOP inogona kuderedza vicar ne3 madhigirii.Iyo plasticizing mhedzisiro yesoya bean mafuta haina kunaka senge yeDOP, asi ine kumwe kugadzikana kwemafuta, izvo zvinozodzikisawo vica yechigadzirwa.Saka pakushandiswa kweplasticizer kunofanirwa kuve nekungwarira zvakanyanya.
