isici

Ukusebenza okuyinhloko

a.Izici zemishini: amandla aphezulu, ukumelana nokukhathala, ukuzinza kwe-dimensional, kanye nokukhasa okuncane (izinguquko ezimbalwa kakhulu ngaphansi kwezimo zokushisa eziphezulu);
b.Ukumelana nokuguga kokushisa: inkomba yokushisa ye-UL ethuthukisiwe ifinyelela ku-120 ~ 140 ℃ (ukuguga kwangaphandle kwesikhathi eside nakho kuhle kakhulu);

c.Ukumelana ne-solvent: akukho ukuqhekeka kwengcindezi;

d.Ukuzinza emanzini: kulula ukubola lapho uthintana namanzi (sebenzisa ukuqapha ekushiseni okuphezulu nasezindaweni ezinomswakama ophezulu);

e.Ukusebenza kukagesi:

1. Ukusebenza kwe-insulation: kuhle kakhulu (kungakwazi ukugcina ukusebenza kukagesi okuzinzile ngisho nangaphansi komswakama kanye nokushisa okuphezulu, kuyimpahla efanelekile yokukhiqiza izingxenye zikagesi nezikagesi);

2. I-Dielectric coefficient: 3.0-3.2;

3. Ukumelana ne-arc: 120s

f.Ukubunjwa kokubunjwa: ukubumba komjovo noma ukubunjwa kwe-extrusion ngemishini evamile.Ngenxa yejubane elisheshayo lokucwebezela kanye noketshezi oluhle, izinga lokushisa lesikhunta nalo liphansi kunelamanye amapulasitiki obunjiniyela.Lapho ucubungula izingxenye ezinezindonga ezincane, kuthatha imizuzwana embalwa, futhi kuthatha kuphela ama-40-60 ezingxenyeni ezinkulu.

isicelo

a.Imishini ye-elekthronikhi: izixhumi, izingxenye zokushintsha, izinto zikagesi zasendlini, izingxenye zokufinyelela, izembozo ezincane zikagesi noma (ukumelana nokushisa, ukumelana nomlilo, ukufakwa kukagesi, ukubunjwa kokubumba);

b.Imoto:

1. Izingxenye zangaphandle: ikakhulukazi zihlanganisa amagridi ekhona, isembozo se-injini, njll.;

2. Izingxenye zangaphakathi: ikakhulukazi zihlanganisa ukuhlala kwe-endoscope, abakaki be-wiper kanye nama-valve esistimu yokulawula;

3. Izingxenye zikagesi zezimoto: i-automotive ignition coil amashubhu asontekile nezixhumi ezihlukahlukene zikagesi, njll.

c.Imishini yemishini: ibhande lokushayela ibhande lerekhoda yevidiyo, isembozo sekhompyutha kagesi, isembozo sesibani semercury, isembozo sensimbi kagesi, izingxenye zomshini wokubhaka kanye nenani elikhulu lamagiya, amakhamera, izinkinobho, amawashi kagesi, izingxenye zekhamera ( ngokumelana nokushisa, izidingo zokubuyiswa komlilo)

Ukuhlanganisa

Ngokuya ngezidingo ezahlukahlukene, ungakhetha ama-adhesive alandelayo:

1. G-955: Ukushisa kwegumbi okuyingxenye eyodwa elapha ukunamathiswa okuthambile okunwebekayo okuqinile, ukumelana nezinga lokushisa eliphezulu neliphansi, kodwa isivinini sokubopha sihamba kancane, ingcina ngokuvamile ithatha usuku olungu-1 noma izinsuku ezimbalwa ukuze yelapheke.

2. I-adhesive esheshayo ye-KD-833 ingabopha ngokushesha ipulasitiki ye-PS ngemizuzwana embalwa noma amashumi amasekhondi, kodwa ungqimba olunamathelayo luqinile futhi luyashwabana, futhi alumelani nokucwiliswa kwamanzi ashisayo ngaphezu kwama-degree angu-60.

3. I-QN-505, i-glue enezingxenye ezimbili, ungqimba oluthambile lweglue, olufanele i-PS indawo enkulu yokubopha noma ukuhlanganisa.Kodwa izinga lokushisa eliphakeme liphansi.

4. I-QN-906: Iglue yezingxenye ezimbili, ukumelana nokushisa okuphezulu.

5. G-988: I-vulcanizate yegumbi enengxenye eyodwa kwezinga lokushisa.Ngemuva kokwelapha, iyi-elastomer ene-adhesive enhle kakhulu engangeni manzi, i-shockproof, ukumelana nokushisa okuphezulu nokuphansi.Uma ubukhulu bungu-1-2mm, buzophulukisa emahoreni angu-5-6 futhi bunamandla athile.Kuthatha okungenani amahora angama-24 ukwelapha ngokuphelele.Ingxenye eyodwa, asikho isidingo sokuxuba, vele usebenzise ngemuva kokukhipha futhi uyivumele ime ngaphandle kokushisisa.

6. I-KD-5600: Ingcina ye-UV elaphayo, ehlanganisa amashidi namapuleti e-PS abonisa ngale, ayikwazi ukuzuza umkhondo, idinga ukuphulukiswa ukukhanya kwe-ultraviolet.Umphumela muhle ngemva kokunamathela.Kodwa izinga lokushisa eliphakeme liphansi.

Ukusebenza okubalulekile

I-insulation kagesi enhle kakhulu (ikakhulukazi i-high-frequency insulation), engenambala futhi esobala, ukukhanya okudluliseka okwesibili ngemuva kwe-plexiglass, umbala, ukumelana namanzi, ukusimama okuhle kwamakhemikhali, amandla amaphakathi, kodwa ama-brittle, kulula ukubanga ukuqina kwengcindezi, nokungabekezelelani Izinyibilikisi ze-organic njenge-benzene. kanye nophethiloli.Ifanele ukwenza i-insulating izingxenye ezibonisa ngale, izingxenye zokuhlobisa, amathuluzi amakhemikhali, izinsimbi ezibonakalayo nezinye izingxenye.

Ukwakha ukusebenza

⒈Impahla ye-amorphous, ukumuncwa komswakama ophansi, ayidingi ukomiswa ngokugcwele, futhi akulula ukubola, kodwa i-coefficient yokwanda okushisayo inkulu, futhi kulula ukukhiqiza ukucindezeleka kwangaphakathi.Inomanzi futhi ingabunjwa ngomshini wokujova isikulufu noma we-plunger.

⒉Kutuswa ukusebenzisa izinga lokushisa eliphezulu lempahla, izinga lokushisa eliphezulu lokukhunta, nomfutho ophansi womjovo.Ukwandisa isikhathi somjovo kunenzuzo ukunciphisa ukucindezeleka kwangaphakathi futhi kuvimbele ukuncipha nokuguqulwa.

⒊Izinhlobo ezahlukene zamasango zingasetshenziswa, futhi amasango axhunywe ne-arc izingxenye zepulasitiki ukugwema ukulimala ezingxenyeni zepulasitiki lapho isango lisuswa.I-engeli yokudilika inkulu futhi i-ejection ifana.Ubukhulu bodonga bezingxenye zepulasitiki bufana, okungcono ngaphandle kokufaka, njengokuthi Ezinye izinto ezifakiwe kufanele zishiswe ngaphambili.

sebenzisa

I-PS isetshenziswa kakhulu embonini ye-optical ngenxa yokudlulisa ukukhanya okuhle.Ingasetshenziselwa ukukhiqiza ingilazi yokubona nezinsimbi ezibonakalayo, kanye nemibala esobala noma egqamile, njengemithunzi yezibani, izinto ezisebenza ngokukhanyisa, njll. I-PS ingaphinda ikhiqize izingxenye zikagesi nezinsimbi eziningi ezisebenza endaweni enemvamisa ephezulu.Njengoba ipulasitiki ye-PS iyinto engaphezulu okunzima ukuyingenisa, kuyadingeka ukusebenzisa iglue ye-PS yobungcweti ukuze uboshwe embonini.

Ukusebenzisa i-PS kukodwa njengomkhiqizo kune-brittleness ephezulu.Ukwengeza inani elincane lezinye izinto ku-PS, njenge-butadiene, kunganciphisa kakhulu ukonakala futhi kuthuthukise ukuqina komthelela.Le pulasitiki ibizwa ngokuthi i-PS-resistant PS, futhi izakhiwo zayo zemishini zithuthukiswa kakhulu.Izingxenye eziningi zemishini nezakhi ezisebenza kahle kakhulu zenziwe ngamapulasitiki.
