Main performance

a.Mechanical properties: simba rakakwirira, kuramba kuneta, kugadzikana kwedimensional, uye zviduku zvinokambaira (zvishoma zvishoma zvinoshanduka pasi pemamiriro ekupisa);
b.Kupisa kuchembera kuramba: iyo yakakwidziridzwa UL tembiricha index inosvika 120 ~ 140 ℃ (kuchembera kwekunze kwenguva refu zvakare kwakanaka kwazvo);

c.Solvent resistance: hapana kushungurudzika kutsemuka;

d.Kugadzikana kumvura: nyore kuparara mukubatana nemvura (shandisa kuchenjerera mukupisa kwepamusoro uye nzvimbo dzakakwirira dzehunyoro);

e.Kuita kwemagetsi:

1. Insulation performance: yakanakisa (inogona kuchengetedza yakagadzikana kushanda kwemagetsi kunyange pasi pehunyoro uye kupisa kwepamusoro, chinhu chakanaka chekugadzira zvikamu zvemagetsi nemagetsi);

2. Dielectric coefficient: 3.0-3.2;

3. Arc kuramba: 120s

f.Molding processability: jekiseni kuumba kana extrusion kuumbwa neyakajairwa michina.Nekuda kwekukurumidza crystallization kumhanya uye kunaka fluidity, tembiricha ye mold zvakare yakadzikira pane yemamwe mainjiniya epurasitiki.Paunenge uchigadzira zvikamu zvakatetepa-madziro, zvinongotora masekondi mashoma, uye zvinongotora 40-60s yezvikamu zvakakura.

application

a.Zvishandiso zvemagetsi: zvinobatanidza, chinja zvikamu, midziyo yemumba, midziyo yekuwedzera, zvivharo zvidiki zvemagetsi kana (kupisa kupisa, kuramba kwemoto, kuvharwa kwemagetsi, kuumba processability);

b.Motokari:

1. Zvikamu zvekunze: kunyanya zvinosanganisira magidhi emakona, injini yekuvhara chivharo, nezvimwewo;

2. Zvikamu zvemukati: kunyanya zvinosanganisira endoscope kugara, wiper brackets uye control system valves;

3. Zvikamu zvemagetsi zvemotokari: motokari yemoto coil yakamonyoroka machubhu uye akasiyana-siyana emagetsi ekubatanidza, nezvimwe.

c.Mechanical midziyo: bhandi rekutyaira shaft yevhidhiyo tepi rekodhi, chivharo chekombuta yemagetsi, chivharo chemwenje chemercury, chivharo chesimbi yemagetsi, zvikamu zvemuchina wekubikira uye huwandu hukuru hwemagiya, makamera, mabhatani, mavhavha ewachi emagetsi, zvikamu zvekamera ( nekudzivirira kupisa, Flame retardant zvinodiwa)

Bonding

Zvinoenderana nezvinodiwa zvakasiyana, unogona kusarudza anotevera adhesives:

1. G-955: Imwe-chikamu tembiricha yekamuri inorapa yakapfava elastic shockproof adhesive, isingaenderane nepamusoro uye yakaderera tembiricha, asi kukurumidza kwekubatanidza kunononoka, glue kazhinji inotora zuva 1 kana mazuva akati wandei kurapa.

2. KD-833 instant adhesive inogona kukurumidza kusungira PS plastiki mumasekonzi mashomanana kana makumi emasekonzi, asi iyo yekunamatira layer yakaoma uye ine brittle, uye haidziviriri kunyudzwa kwemvura inopisa pamusoro pe60 degrees.

3. QN-505, maviri-component glue, soft glue layer, yakakodzera PS nzvimbo huru yekubatanidza kana kusanganisa.Asi kupikisa kwekushisa kwepamusoro kwakashata.

4. QN-906: Zviviri-chikamu glue, kupisa kwakanyanya.

5. G-988: Imwe-chikamu chekamuri tembiricha vulcanizate.Mushure mekurapa, iyo elastomer ine yakanakisa kusapinda kwemvura, shockproof adhesive, yakakwirira uye yakaderera tembiricha kuramba.Kana ukobvu huri 1-2mm, huchapora mumaawa mashanu-6 uye hune rimwe simba.Zvinotora angangoita maawa makumi maviri nemana kuti zvipere zvakakwana.Single-chikamu, hapana chikonzero chekusanganisa, ingo shandisa mushure me extruding uye rega imire pasina kudziyisa.

6. KD-5600: UV kurapa adhesive, bonding läpinäkyvä PS mashizha uye mahwendefa, anogona kuwana hapana trace effect, inoda kurapwa ne ultraviolet chiedza.Mhedzisiro yacho yakanaka mushure mekunamatira.Asi kupikisa kwekushisa kwepamusoro kwakashata.

Kuita kwezvinhu

Yakanakisa magetsi ekudzivirira (kunyanya high-frequency insulation), isina ruvara uye yakajeka, light transmittance yechipiri chete kune plexiglass, coloration, kusamira kwemvura, kugadzikana kwakanaka kwemakemikari, avhareji simba, asi brittle, nyore kukonzera kusagadzikana brittleness, uye kusashivirira Organic solvents senge benzene. uye peturu.Inokodzera kugadzira insulating transparent parts, decoration parts, chemical instruments, Optical instruments nezvimwe zvikamu.

Kugadzira kuita

⒈Amorphous zvinhu, kunyura kwakadzika, hazvidi kuomeswa zvakakwana, uye hazvisi nyore kuora, asi coefficient yekuwedzera kwekushisa yakakura, uye zviri nyore kubudisa kushushikana kwemukati.Iyo ine mvura yakanaka uye inogona kuumbwa ne screw kana plunger jekiseni muchina.

⒉Zvinokurudzirwa kushandisa tembiricha yepamusoro, tembiricha yakakwira mold, uye kuderera kwejekiseni.Kuwedzera nguva yejekiseni kunobatsira kuderedza kushushikana kwemukati uye kudzivirira shrinkage uye deformation.

⒊Mafomu akasiyana-siyana emagedhi anogona kushandiswa, uye masuwo akabatanidzwa nezvikamu zvepurasitiki arc kudzivirira kukanganisa kune zvikamu zvepurasitiki kana gedhi rabviswa.Demolding angle yakakura uye ejection iri yunifomu.Ukobvu hwemadziro ezvikamu zvepurasitiki yunifomu, zviri nani pasina kuisa, senge Zvimwe zvinoisa zvinofanirwa kuve zvakafanopiswa.

use

PS inoshandiswa zvakanyanya muindasitiri yemaziso nekuda kwekunaka kwayo kufambiswa kwechiedza.Inogona kushandiswa kugadzira optical glass uye optical instruments, pamwe chete nemavara akajeka kana akajeka, akadai semwenje, midziyo yemagetsi, nezvimwewo. PS inogonawo kubudisa zvinhu zvakawanda zvemagetsi uye zvishandiso zvinoshanda munzvimbo yakakwirira-frequency.Sezvo PS plastiki iri yakaoma-ku-inert pamusoro pezvinhu, zvinodikanwa kushandisa nyanzvi PS glue kusungira muindasitiri.

Kushandisa PS chete sechigadzirwa kune yakakwirira brittleness.Kuwedzera huwandu hudiki hwezvimwe zvinhu kuPS, senge butadiene, zvinogona kuderedza zvakanyanya brittleness uye kunatsiridza kuoma kwemaitiro.Plastiki iyi inodaidzwa kuti impact-resistant PS, uye michina yayo inovandudzwa zvakanyanya.Mazhinji mamechani zvikamu uye zvikamu zvine mashandiro akanaka anogadzirwa kubva kumapurasitiki.
