uphawu

Ukusebenza okuphambili

a.Iimpawu zomatshini: amandla aphezulu, ukuxhathisa ukukhathala, ukuzinza kwe-dimensional, kunye ne-creep encinci (utshintsho olumbalwa kakhulu phantsi kweemeko eziphezulu zokushisa);
b.Ukumelana nokuguga kobushushu: isalathiso sobushushu esiphuculweyo se-UL sifikelela kwi-120 ~ 140 ℃ (ixesha elide ukuguga kwangaphandle nako kuhle kakhulu);

c.Ukumelana ne-solvent: akukho xinzelelo lokuqhekeka;

d.Ukuzinza kumanzi: kulula ukubola xa udibana namanzi (sebenzisa isilumkiso kwiqondo lokushisa eliphezulu kunye neendawo eziphezulu zokufuma);

e.Ukusebenza kombane:

1. Ukusebenza kwe-insulation: egqwesileyo (inokugcina ukusebenza kombane okuzinzile naphantsi komswakama kunye nobushushu obuphezulu, yinto efanelekileyo yokuvelisa iindawo zombane kunye nombane);

2. I-coefficient ye-Dielectric: 3.0-3.2;

3. Ukuchasana kweArc: 120s

f.Ukubunjwa kwe-processability: isitofu sokubumba okanye ukubunjwa kwe-extrusion ngezixhobo eziqhelekileyo.Ngenxa yesantya secrystallization ekhawulezayo kunye nolwelo olulungileyo, ubushushu bomngundo bukwangaphantsi kunezinye iiplastiki zobunjineli.Xa ulungisa iindawo ezinodonga oluncinci, kuthatha imizuzwana embalwa, kwaye kuthatha kuphela i-40-60s kwiindawo ezinkulu.

isicelo

a.Izixhobo zombane: izihlanganisi, iinxalenye zokutshintsha, izixhobo zasekhaya, izixhobo zokuncedisa, iikhava zombane ezincinci okanye (ukumelana nobushushu, ukumelana nomlilo, ukugqunywa kombane, ukubunjwa kombane);

b.Imoto:

1. Amalungu angaphandle: ikakhulu abandakanya iigridi zekona, i-injini yokuvala i-injini, njl.;

2. Amalungu angaphakathi: ikakhulu abandakanya ukuhlala kwe-endoscope, izibiyeli zokucima kunye neevalvu zesistim yokulawula;

3. Amalungu ombane we-Automotive: i-automotive ignition coil twist tubes kunye nezixhumi ezahlukeneyo zombane, njl.

c.Izixhobo zoomatshini: ishafti yebhanti yokuqhuba irekhoda yevidiyo, isigqubuthelo sekhompyuter, isibane sesibane semercury, isigqubuthelo sentsimbi sombane, iinxalenye zoomatshini bokubhaka kunye nenani elikhulu leegiya, iikhamera, amaqhosha, iiwotshi zewotshi zombane, iinxalenye zekhamera ( ngokuxhathisa ubushushu, iimfuno zeFlame retardant)

Ukudibanisa

Ngokweemfuno ezahlukeneyo, unokukhetha ezi zincamathelisi zilandelayo:

1. G-955: Ubushushu begumbi elinye-icandelo elinyanga i-adhesive ethambileyo ye-elastic shockproof, ukumelana nobushushu obuphezulu kunye nesezantsi, kodwa isantya sokubopha sicotha, iglu idla ngokuthatha usuku olu-1 okanye iintsuku ezininzi ukunyanga.

2. I-adhesive ye-KD-833 ekhawulezayo inokukhawuleza idibanise iplastiki ye-PS kwimizuzwana embalwa okanye imizuzwana yamashumi, kodwa i-adhesive layer ilukhuni kwaye i-brittle, kwaye ayixhathisi ukuntywiliselwa kwamanzi ashushu ngaphezu kwama-60 degrees.

3. I-QN-505, i-glue yamacandelo amabini, i-soft glue layer, ifanelekile kwi-PS indawo enkulu yokudibanisa okanye ukudibanisa.Kodwa ukumelana nobushushu obuphezulu kubi.

4. I-QN-906: I-glue yamacandelo amabini, ukumelana nokushisa okuphezulu.

5. G-988: Ubushushu begumbi elinye-icandelo vulcanizate.Emva kokunyanga, yi-elastomer ebalaseleyo ekungangeni manzi, ukuncamathelisa okungangenwa kukothuka, ukumelana nobushushu obuphezulu kunye nokusezantsi.Ukuba ubukhulu buyi-1-2mm, buya kunyanga kwiiyure ezingama-5-6 kwaye bunamandla athile.Kuthatha ubuncinane iiyure ezingama-24 ukunyanga ngokupheleleyo.I-single-component, akukho mfuneko yokuxuba, sebenzisa nje emva kokukhupha kwaye uyivumele ime ngaphandle kokufudumeza.

6. I-KD-5600: I-UV yokunyanga i-adhesive, i-bonding transparent PS sheets kunye neepleyiti, ayinakufezekisa akukho mphumo, idinga ukunyangwa kukukhanya kwe-ultraviolet.Isiphumo sihle emva kokunamathela.Kodwa ukumelana nobushushu obuphezulu kubi.

Ukusebenza kwezinto eziphathekayo

Ukugqunywa kombane okugqwesileyo (ingakumbi i-high-frequency insulation), ayinambala kwaye icace, ukukhanya okudlula okwesibini kuphela kwiplexiglass, umbala, ukuxhathisa kwamanzi, uzinzo oluhle lweekhemikhali, amandla aphakathi, kodwa anqabileyo, kulula ukwenza uxinzelelo, kunye nokunganyamezeli Izinyibilikisi ze-Organic ezifana nebenzene. kunye nepetroli.Ifanelekile ukwenza i-insulating transparent parts, iindawo zokuhombisa, izixhobo zekhemikhali, izixhobo ze-optical kunye nezinye iindawo.

Ukwenza umsebenzi

- Izinto ze-Amorphous, ukufunxa okuphantsi komswakama, akufuneki ukuba zomiswe ngokupheleleyo, kwaye akulula ukubola, kodwa i-coefficient yokwandiswa kwe-thermal inkulu, kwaye kulula ukuvelisa uxinzelelo lwangaphakathi.Inomanzi kwaye inokubunjwa ngesikrufu okanye umatshini wokutofa weplunger.

⒉Kucetyiswa ukuba usebenzise ubushushu obuphezulu besixhobo, ubushushu obuphezulu bokungunda, kunye noxinzelelo lwenaliti ephantsi.Ukwandisa ixesha lokutofa kunenzuzo ekunciphiseni uxinzelelo lwangaphakathi kunye nokuthintela ukuncipha kunye nokuguqulwa.

⒊Iindlela ezahlukeneyo zamasango zingasetyenziswa, kwaye amasango adityaniswe kunye neentsimbi zeplastiki ukuphepha umonakalo kwiindawo zeplastiki xa isango lisusiwe.I-angle ye-demolding inkulu kwaye i-ejection ifana.Ubunzima bodonga lwamacandelo eplastiki bufana, ngokufanelekileyo ngaphandle kokufakwa, okufana nokufakela okunye kufuneka kufudunyezwe.

sebenzisa

I-PS isetyenziswa kakhulu kwishishini le-optical ngenxa yokuhambisa ukukhanya okuhle.Ingasetyenziselwa ukwenza iglasi ye-optical kunye nezixhobo zokukhanya, kunye nemibala ecacileyo okanye eqaqambileyo, njengemithunzi yezibane, izixhobo zokukhanyisa, njl.Ekubeni iplastiki ye-PS yinto enzima-ukungena-inert ebusweni, kuyimfuneko ukusebenzisa i-PS glue yobugcisa ukuze udibanise kwishishini.

Ukusebenzisa i-PS yodwa njengemveliso ine-brittleness ephezulu.Ukongeza inani elincinci lezinye izinto kwi-PS, ezifana ne-butadiene, kunokunciphisa kakhulu i-brittleness kunye nokuphucula ukuqina kwempembelelo.Le plastiki ibizwa ngokuba yi-PS enganyangekiyo kwimpembelelo, kwaye iimpawu zayo zomatshini ziphuculwe kakhulu.Amalungu amaninzi oomatshini kunye namacandelo asebenza ngokugqwesileyo enziwe kwiiplastiki.
