Umsebenzi ophambili

a. Iimpawu zoomatshini: amandla aphezulu, ukumelana nokudinwa, uzinzo olunobukhulu, kunye nokurhubuluza okuncinci (utshintsho oluncinci kakhulu phantsi kweemeko zobushushu obuphezulu);
b. Ukumelana nokuguga kobushushu: i-UL temperature index ephuculweyo ifikelela kwi-120~140℃ (ukuguga ngaphandle ixesha elide nako kulungile kakhulu);

c. Ukumelana nesinyibilikisi: akukho kuqhekeka koxinzelelo;

d. Uzinzo emanzini: kulula ukubola xa udibana namanzi (qaphela xa kukho amaqondo obushushu aphezulu kunye nomswakama ophezulu);

e. Ukusebenza kombane:

1. Ukusebenza kwe-insulation: igqwesileyo (ingagcina ukusebenza kombane okuzinzileyo nokuba kuphantsi komswakama kunye nobushushu obuphezulu, sisixhobo esifanelekileyo sokwenza izixhobo ze-elektroniki kunye nezombane);

2. I-dielectric coefficient: 3.0-3.2;

3. Ukumelana ne-arc: 120s

f. Ukukwazi ukubumba: ukubumba ngenaliti okanye ukubumba nge-extrusion kusetyenziswa izixhobo eziqhelekileyo. Ngenxa yesantya esikhawulezayo sokwenza ikristale kunye nokugeleza okuhle, ubushushu bokubumba buphantsi kunobo bezinye iiplastiki zobunjineli. Xa kucutshungulwa iindawo ezixineneyo, kuthatha imizuzwana embalwa kuphela, kwaye kuthatha imizuzwana engama-40-60 kuphela kwiindawo ezinkulu.

isicelo

a. Izixhobo ze-elektroniki: izihlanganisi, iindawo zokutshintsha, izixhobo zasekhaya, iindawo ezincedisayo, izigqubuthelo zombane ezincinci okanye (ukuxhathisa ubushushu, ukuxhathisa ilangatye, ukugquma kombane, ukukwazi ukubumba izinto ngendlela efanelekileyo);

b. Imoto:

1. Iindawo zangaphandle: ziquka ikakhulu iigridi zekona, isigqubuthelo somoya wenjini, njl.njl.;

2. Iindawo zangaphakathi: ikakhulu ziquka ukuhlala kwe-endoscope, izibiyeli ze-wiper kunye neevalvu zenkqubo yokulawula;

3. Iindawo zombane zezithuthi: iityhubhu ezijijekileyo ze-ignition coil zezithuthi kunye nezihlanganisi ezahlukeneyo zombane, njl.

c. Izixhobo zoomatshini: i-belt drive shaft ye-video tape recorder, i-electronic computer cover, i-mercury lamp cover, i-electric iron cover, iindawo zomatshini wokubhaka kunye nenani elikhulu leegiya, ii-cam, amaqhosha, ii-electronic watch casings, iindawo zekhamera (ezinokumelana nobushushu, iimfuno ze-Flame retardant)

Ukubopha

Ngokweemfuno ezahlukeneyo, ungakhetha ezi zincamathelisi zilandelayo:

1. G-955: Iglu ethambileyo nethambileyo enamathelayo eqinisa ubushushu begumbi, enganyangekiyo kubushushu obuphezulu nobuphantsi, kodwa isantya sokubopha sicotha, iglu idla ngokuthatha usuku olunye okanye iintsuku ezimbalwa ukunyanga.

2. I-KD-833 i-adhesive ekhawulezileyo inokubopha ngokukhawuleza iplastiki ye-PS kwimizuzwana embalwa okanye imizuzwana elishumi, kodwa umaleko we-adhesive uqinile kwaye uyaphuka, kwaye awuxhathisi ukuntywiliselwa emanzini ashushu ngaphezu kwama-60 degrees.

3. QN-505, iglu enamacandelo amabini, umaleko weglue ethambileyo, ifanelekile kwi-PS enkulu okanye ukudibanisa indawo. Kodwa ukumelana nobushushu obuphezulu akukuhle.

4. QN-906: Iglu enamacandelo amabini, ukumelana nobushushu obuphezulu.

5. G-988: I-vulcanizate yobushushu begumbi enenxalenye enye. Emva kokunyibilika, yi-elastomer ene-adhesive engangeni manzi, enganyangekiyo, enokuxhathisa ubushushu obuphezulu nobuphantsi. Ukuba ubukhulu bayo buyi-1-2mm, iya kunyibilika kwiiyure ezi-5-6 kwaye inamandla athile. Kuthatha ubuncinane iiyure ezingama-24 ukunyibilika ngokupheleleyo. Inenxalenye enye, akukho mfuneko yokuxuba, yifake nje emva kokuyikhupha kwaye uyivumele ime ngaphandle kokufudumeza.

6. KD-5600: Iglu yokuncamathelisa i-UV, amashiti kunye neepleyiti zePS ezicacileyo ezibophayo, azinakufumana siphumo silandelekayo, kufuneka zinyangwe kukukhanya kwe-ultraviolet. Isiphumo siba sihle emva kokuncamathela. Kodwa ukumelana nobushushu obuphezulu akukuhle.

Ukusebenza kwezinto ezibonakalayo

Ubushushu obugqwesileyo bombane (ingakumbi ubushushu obuphezulu), obungenambala nobucacileyo, ukuhanjiswa kokukhanya kulandelayo kuphela emva kwe-plexiglass, umbala, ukumelana namanzi, uzinzo oluhle lweekhemikhali, amandla aphakathi, kodwa abuthathaka, kulula ukubangela uxinezeleko olubuthathaka, kunye nokunganyamezelani Izinyibilikisi zendalo ezifana ne-benzene kunye nepetroli. Zifanelekile ukwenza iindawo ezikhuselayo ezibonakalayo, iindawo zokuhombisa, izixhobo zeekhemikhali, izixhobo ze-optical kunye nezinye iindawo.

Ukwakha ukusebenza

Izinto ezi-⒈Amorphous, ezifunxa umswakama omncinci, akufuneki zomiswe ngokupheleleyo, kwaye azilula ukubola, kodwa i-coefficient yokwandiswa kobushushu inkulu, kwaye kulula ukuvelisa uxinzelelo lwangaphakathi. Inokutyibilika okuhle kwaye inokubunjwa nge-screw okanye umatshini wokujova i-plunger.

⒉Kucetyiswa ukuba kusetyenziswe ubushushu obuphezulu bezinto, ubushushu obuphezulu bokubumba, kunye noxinzelelo oluphantsi lokufaka. Ukwandisa ixesha lokufaka inaliti kuluncedo ekunciphiseni uxinzelelo lwangaphakathi kunye nokuthintela ukushwabana kunye nokuguquguquka.

⒊Kungasetyenziswa iintlobo ngeentlobo zamasango, kwaye amasango adityaniswe ne-arc yeendawo zeplastiki ukuze kuthintelwe ukonakala kweendawo zeplastiki xa isango lisuswa. I-engile yokudiliza inkulu kwaye ukuphuma kwayo kuyafana. Ubukhulu bodonga lweendawo zeplastiki buyafana, kungcono ukuba kungabikho zinto zokufaka, ezifana nezinye izinto zokufaka kufuneka zitshiswe ngaphambili.

sebenzisa

I-PS isetyenziswa kakhulu kwishishini le-optical ngenxa yokuhambisa kwayo ukukhanya okuhle. Ingasetyenziselwa ukuvelisa izixhobo zeglasi ezikhanyayo kunye nezixhobo ze-optical, kunye nemibala ecacileyo okanye ekhanyayo, efana nezikhanyiso zezibane, izixhobo zokukhanyisa, njl. I-PS inokuvelisa nezinto ezininzi zombane kunye nezixhobo ezisebenza kwindawo ehlala ixesha elide. Ekubeni iplastiki ye-PS iyinto engaphezulu enzima ukuyicoca, kuyimfuneko ukusebenzisa iglu ye-PS yobungcali ukuze ibotshelelwe kwishishini.

Ukusebenzisa i-PS yodwa njengemveliso kunokubangela ukuba i-fragment ephezulu. Ukongeza inani elincinci lezinye izinto kwi-PS, ezifana ne-butadiene, kunokunciphisa kakhulu ukufragment kwaye kuphucule ukuqina kwe-impact. Le plastiki ibizwa ngokuba yi-PS enganyangekiyo, kwaye iimpawu zayo ze-mechanical ziphuculwe kakhulu. Iindawo ezininzi ze-mechanical kunye nezinto ezisebenza kakuhle zenziwe ngeplastiki.
