Ukusebenza okuyinhloko

a. Izakhiwo zemishini: amandla aphezulu, ukumelana nokukhathala, ukuzinza kobukhulu, kanye nokukhukhuleka okuncane (izinguquko ezimbalwa kakhulu ngaphansi kwezimo zokushisa okuphezulu);
b. Ukumelana nokuguga kokushisa: inkomba yokushisa ye-UL ethuthukisiwe ifinyelela ku-120 ~ 140℃ (ukuguga kwangaphandle isikhathi eside nakho kuhle kakhulu);

c. Ukumelana nesinyibilikisi: akukho ukuqhekeka kokucindezeleka;

d. Ukuqina kwamanzi: kulula ukubola uma uthintana namanzi (qaphela ezindaweni ezinokushisa okuphezulu kanye nomswakama ophezulu);

e. Ukusebenza kukagesi:

1. Ukusebenza kokuvikela: okuhle kakhulu (kungagcina ukusebenza kukagesi okuzinzile ngisho nangaphansi komswakama kanye nokushisa okuphezulu, kuyinto efanelekile yokukhiqiza izingxenye zikagesi neze-elekthronikhi);

2. I-dielectric coefficient: 3.0-3.2;

3. Ukumelana ne-arc: 120s

f. Ukucutshungulwa kokubumba: ukubumba ngomjovo noma ukubumba ngemishini ejwayelekile. Ngenxa yesivinini esisheshayo sokukristala kanye nokugeleza okuhle, izinga lokushisa lokubumba nalo liphansi kunelezinye ipulasitiki zobunjiniyela. Lapho kucutshungulwa izingxenye ezinezindonga ezincane, kuthatha imizuzwana embalwa kuphela, futhi kuthatha amasekhondi angu-40-60 kuphela ezingxenyeni ezinkulu.

isicelo

a. Izinto zikagesi: izixhumi, izingxenye zokushintsha, izinto zasekhaya, izingxenye zezesekeli, izembozo zikagesi ezincane noma (ukumelana nokushisa, ukumelana nomlilo, ukufudumala kukagesi, ukucutshungulwa kokubumba);

b. Imoto:

1. Izingxenye zangaphandle: zifaka phakathi amagridi asemakhoneni, isembozo somoya wenjini, njll.;

2. Izingxenye zangaphakathi: ikakhulukazi zifaka phakathi ukuhlala kwe-endoscope, amabhuleki e-wiper kanye nama-valve esistimu yokulawula;

3. Izingxenye zikagesi zezimoto: amashubhu asontekile e-ignition coil yezimoto kanye nezixhumi zikagesi ezahlukahlukene, njll.

c. Imishini yomshini: umphini wokushayela ibhande we-video tape recorder, isembozo sekhompyutha kagesi, isembozo sesibani se-mercury, isembozo sensimbi kagesi, izingxenye zomshini wokubhaka kanye nenani elikhulu lamagiya, amakhamera, izinkinobho, amabhokisi ewashi kagesi, izingxenye zekhamera (ezinokumelana nokushisa, izidingo zokuvimbela ilangabi)

Ukubopha

Ngokuya ngezidingo ezahlukene, ungakhetha izinamathiselo ezilandelayo:

1. G-955: Ingcina ethambile neqinile eqinisayo ebamba ukushisa kwegumbi enesici esisodwa, emelana nokushisa okuphezulu nokuphansi, kodwa ijubane lokubopha lihamba kancane, ingcina ivame ukuthatha usuku olulodwa noma izinsuku eziningana ukuze iphole.

2. I-KD-833 i-instant glue ingabopha ngokushesha ipulasitiki ye-PS ngemizuzwana embalwa noma amashumi emizuzwana, kodwa ungqimba lwe-glue luqinile futhi luyaphuka, futhi alumelani nokucwiliswa emanzini ashisayo ngaphezu kwama-degrees angu-60.

3. I-QN-505, iglue enezingxenye ezimbili, ungqimba lweglue oluthambile, olufanelekela ukubopha noma ukuhlanganisa indawo enkulu ye-PS. Kodwa ukumelana nokushisa okuphezulu akukuhle.

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

5. G-988: I-vulcanizate yokushisa kwegumbi enengxenye eyodwa. Ngemva kokuqiniswa, iyi-elastomer enesinamathiseli esingangeni manzi esihle kakhulu, esingangenwa ukushaqeka, ukumelana nokushisa okuphezulu nokuphansi. Uma ubukhulu bungu-1-2mm, izoqiniswa emahoreni angu-5-6 futhi inamandla athile. Kuthatha okungenani amahora angu-24 ukupholisa ngokuphelele. Ingxenye eyodwa, asikho isidingo sokuxuba, faka nje ngemva kokuyikhipha bese uyivumela ime ngaphandle kokushisa.

6. KD-5600: Ingcina yokwelapha i-UV, amashidi namapuleti e-PS abonakalayo okubopha, ayikwazi ukufeza umphumela omncane, idinga ukwelashwa ngokukhanya kwe-ultraviolet. Umphumela muhle ngemva kokunamathela. Kodwa ukumelana nokushisa okuphezulu kubi.

Ukusebenza kwezinto ezibonakalayo

Ukushisa okukagesi okuhle kakhulu (ikakhulukazi ukushisa okuvama kakhulu), okungenambala futhi okubonakalayo, ukudlulisa ukukhanya okulandela i-plexiglass kuphela, umbala, ukumelana namanzi, ukuzinza okuhle kwamakhemikhali, amandla ajwayelekile, kodwa okubuthakathaka, okulula ukubangela ukucindezeleka ukubuthakathaka, kanye nokungabekezeleli izinyibilikisi eziphilayo ezifana ne-benzene nephethiloli. Kufanelekela ukwenza izingxenye ezisobala ezivikela ukushisa, izingxenye zokuhlobisa, izinsimbi zamakhemikhali, izinsimbi zokukhanya nezinye izingxenye.

Ukwakha ukusebenza

Izinto ezi-⒈Amorphous, ezimunca umswakama omncane, azidingi ukomiswa ngokuphelele, futhi akulula ukubola, kodwa i-coefficient yokwanda kokushisa inkulu, futhi kulula ukukhiqiza ukucindezeleka kwangaphakathi. Inokugeleza okuhle futhi ingabunjwa ngomshini wokujova ngesikulufo noma nge-plunger.

⒉Kuyanconywa ukusebenzisa izinga lokushisa eliphezulu lezinto ezibonakalayo, izinga lokushisa eliphezulu lesikhunta, kanye nomfutho ophansi wokujova. Ukwandisa isikhathi sokujova kuyasiza ekunciphiseni ukucindezeleka kwangaphakathi nokuvimbela ukushwabana nokuguquka.

⒊Kungasetshenziswa izinhlobo ezahlukene zamasango, futhi amasango axhunywe ne-arc yezingxenye zepulasitiki ukugwema ukulimala kwezingxenye zepulasitiki lapho isango lisuswa. I-engeli yokususa igesi inkulu futhi ukuphuma kwayo kuyafana. Ubukhulu bodonga lwezingxenye zepulasitiki buyafana, kungcono ngaphandle kwezinto zokufaka, njengezinye izinto zokufaka kufanele zishiswe.

sebenzisa

I-PS isetshenziswa kabanzi embonini ye-optical ngenxa yokudlulisa kwayo ukukhanya okuhle. Ingasetshenziswa ukukhiqiza ingilazi ye-optical kanye nezinsimbi ze-optical, kanye nemibala ecacile noma ekhanyayo, njengezibani, izinto zokukhanyisa, njll. I-PS ingakhiqiza futhi izingxenye eziningi zikagesi nezinsimbi ezisebenza endaweni evame kakhulu. Njengoba ipulasitiki ye-PS iyinto engaphezulu okunzima ukuyihlanza, kubalulekile ukusebenzisa iglue ye-PS yobungcweti ukuze ihlanganiswe embonini.

Ukusebenzisa i-PS yodwa njengomkhiqizo kunamandla aphezulu okuphuka. Ukwengeza inani elincane lezinye izinto ku-PS, njenge-butadiene, kunganciphisa kakhulu ukuphuka futhi kuthuthukise ukuqina komthelela. Le pulasitiki ibizwa ngokuthi i-PS engamelani nokuphahlazeka, futhi izakhiwo zayo zomshini zithuthukiswa kakhulu. Izingxenye eziningi zomshini kanye nezingxenye ezisebenza kahle kakhulu zenziwe ngamapulasitiki.
