zvigadzirwa

Mumakore achangopfuura, zvinhu zvisingaremi, zvine kabhoni shoma, uye zvine simba rakawanda zvave zvinhu zvikuru zvitatu zveindasitiri yekugadzira. Kunyangwe zvinhu zvesimbi zvechinyakare zvine simba rakawanda, zvine simba rakawanda, zvinoshandisa simba rakawanda pakugadzira, uye zvinogona kuonda; Kunyangwe mapurasitiki akajairwa egirazi mapfupi akasimbiswa nefiber ane mhedzisiro yakakura yekuderedza huremu, haashande zvakanaka pasi pezvinodiwa zvakaita sekukwanisa kutakura mutoro kwenguva refu, kupisa kwakakwira nekudzika, uye kuomarara kwakanyanya kwakabatana nemadziro matete.

Ndiko kunobva girazi refu rakasimbiswa polypropylene (LGF-PP) uye girazi refu rakasimbiswa polyamide (LGF-PA66) zvinoonekwa seimwe yemhando dziri kukura nekukurumidza mumunda wepurasitiki yakagadziriswa pasi rose. Zvichienderana nehuwandu hweindasitiri, musika wepasi rose wezvinhu zvinosanganiswa negirazi refu rakasimbiswa thermoplastic zvinotarisirwa kukura kubva pamadhora ekuAmerica angangoita mabhiriyoni maviri nehafu muna 2023 kusvika mabhiriyoni mana nehafu emadhora ekuAmerica muna 2030, nekukura kwegore negore kweinenge 7.2%, zvichikonzerwa nemitemo yakareruka uye kumanikidzwa kwemitengo.

一,Mabhenefiti makuru e tekinoroji ekushandisa zvinhu zvegirazi refu zvakasimbiswa nefiber

Kusiyana nemapurasitiki mapfupi egirazi akasimbiswa nefiber (anowanzo kureba 0.2-0.6mm), zvinhu zvegirazi refu zvakasimbiswa nefiber zvinochengetedza kureba kwefiber yegirazi ye10-25mm mu resin matrix kuburikidza nemaitiro akakosha ekuisa impregnation uye extrusion, uye zvinoumba chimiro chenetwork chine mativi matatu mushure mekupinza injection. Zvinofanira kucherechedzwa kuti mwero wekuchengetedza kwechimiro ichi chenetwork unoenderana nekugadzirwa kwescrews uye chimiro chegedhi panguva yekupinza injection; Kana maitiro acho asina kunaka, urefu hwefiberglass hunogona kuramba huchiderera zvakanyanya.

Chimiro ichi chinounza matanho matatu akakosha ekuvandudza mashandiro:

1. Kudzivirira kwakanyanya kwesimba

Network refu yegirazi inogona kudzivirira kupararira kwematombo, uye simba rayo rekukanganisa rakakwira ne40% -80% kupfuura repfupi fiber PP/PA. Patembiricha yakaderera ye -40 ℃, zvinhu zvakajairika zvinogona kutyoka, nepo zvinhu zvegirazi refu fiber zvichiri kugona kuchengetedza anopfuura 80% yekushanda kwazvo pakukanganisa patembiricha yemumba. Data riri pamusoro apa rakavakirwa pamiyero yekuyedza yeISO 179 kana ASTM D256.

2. Kuramba kwakanaka kwazvo uye kugadzikana kwakaenzana

Kana zvinhu zvikasashanda kwenguva refu (sezvakaita mafuremu emotokari nemakumbo ekutsigira zvishandiso zvepamba), zvinhu zvefaibha pfupi zvichashanduka zvakanyanya, nepo zvinhu zvefaibha refu zvichaderedzwa neanopfuura 50% nekuda kwekutsigirwa kwemapfupa efaibha regirazi. Panguva iyi, mukuyedzwa kwekupisa kwakanyanya uye kwakaderera kubva -40 ℃ kusvika 120 ℃, kushanduka kwewarpage kwezvigadzirwa zvefaibha refu regirazi kunongova chikamu chimwe muzvitatu chefaibha pfupi. Izvi zvinoita kuti zvinhu zveLFF zvinyanyokodzera zvikamu zvine tembiricha huru dzekunze.

3. Kubatana kwesimba guru uye huremu

Kuwanda kwesimbi iyi kunongova 1/2-1/3 yealuminium alloy (LGF-PP inenge 1.0-1.2 g/cm³, LGF-PA66 inenge 1.3-1.5 g/cm³), asi simba rayo (simba/huremu) riri pedyo kana kutopfuura mamwe maaluminium alloys, zvichiita kuti ive sarudzo yakanaka yekuwana "kutsiva simbi nepurasitiki". Semuenzaniso, simba rekudhonza reLGF-PP40 rinogona kusvika 120-150 MPa, uye modulus inokotama inogona kusvika 10-12 GPa, iyo yakakwana kutsiva simbi kune zvikamu zvakawanda zvakaumbwa zvishoma.

二,Nzvimbo dzakajairika dzekushandisa uye zvinodiwa zvakananga zvezvinhu mumunda wega wega

Mienzaniso yezvikamu zveindasitiri, zvinodiwa zvikuru, zvinhu zvinokurudzirwa

三Ruzivo rweMaitiro eMusika

Zvichienderana nehuwandu hwevamwe, musika wepasi rose wezvinhu zvinogadzirwa negirazi refu zvakasimbiswa nefiber thermoplastic zvinotarisirwa kusvika mabhiriyoni maviri nehafu emadhora ekuAmerica muna 2023, uye zvinotarisirwa kusvika mabhiriyoni mana nehafu emadhora ekuAmerica panosvika 2030, nekukura kwe7.2% pagore. Data source: Industry reports dzakadai seMarketsandMarkets. Pakati pavo, dunhu reAsia Pacific ndiro rine kukura kwekukurumidza, uye China, semugadziri mukuru uye mutengesi wepurasitiki dzakagadziriswa, iri kutsiva zvishoma nezvishoma zvinhu zvinodhura zvekuEurope neAmerica. Simba guru rinotungamira ikodzero yemutengo (20% -30% yakaderera pane zvigadzirwa zvekuEurope neAmerica) uye kutenderera kupfupi kwekutumira.

四、 Nzvimbo yedu

Kambani yedu yave ichinyanya kutarisa pakutsvaga nekugadzira LGF-PP neLGF-PA66 kwemakore anopfuura makumi maviri, uye ine sisitimu yakazvimirira yekugadzira tekinoroji yekuisa fiber yegirazi refu. Chigadzirwa ichi chakatumirwa kuEurope, Russia, Southeast Asia, Middle East, South America nedzimwe nzvimbo.

Hatizviti tiri isu chete kana kuti takanakisisa, asi tinopa dzimwe nzira dzakasimbiswa. Kana tichienzanisa nemakambani makuru ekuEurope nekuAmerica akadai seSABIC, Celanese, neDSM, mukana wedu wemutengo wakajairika i20% -25%, ukuwo tichichengetedza 85% -95% yekushanda kwayo kwemuchina, izvo zvakasimbiswa kuburikidza nekuyedzwa kwevatengi vakawanda.

Hatingope magiredhi akajairwa chete, asi tinogadzirisawo mafomura zvichienderana nenzvimbo dzekushandiswa kwevatengi (tembiricha yepamusoro neyakaderera, hunyoro, mavara emafuta, kuratidzwa panze), zvichibatsira vatengi kuderedza zvakanyanya mitengo yezvinhu uku vachiona kuti zvinoshanda.Chiitiko chinoshanda: Mafomula akagadzirwa anowanzo da mavhiki mana kusvika matanhatu ekugadzirisa fomura uye kusimbiswa kwemuenzaniso usati watanga kugadzirwa.
