Ityhubhu ye-silicone ye-hydraulic

I-siliconeirabha, into esebenza kakhulu esetyenziswa kakhulu kwi-elektroniki, kwi-aerospace, nakwiindawo zonyango, ibisoloko itsala ingqalelo ngenxa yayo Ubushushu Diimpawu zophuhliso. Ngokuphathelele umbuzo wokuba ingabai-siliconeIrabha iyancipha xa ibekwe kubushushu, uphando lwakutshanje kunye nemizekelo yobugcisa ibonisa ukuba irabha evulcanized i-siliconeirabha ibonakalisa kakuhle kakhuluUbushushu beT uzinzo. Kumaqondo obushushu aphezulu, ngokuyintloko ibonisa ukwanda kobushushu, hayi ukuncitshiswa. Ukuncitshiswa kwayo okuthe ngqo kuphantsi kakhulu, kwaye nokuba "kuncitshiswa okungekho" kunokufezekiswa ngeendlela zokuguqula.

一．Iingcamango Ezingachanekanga Nenyaniso Yesayensi

Kubomi bemihla ngemihla, izinto ezininzi zifumana ukucutheka okubonakalayo xa zishushu, nto leyo ekhokelela kwingcamango yokuba ziyacutheka xa zishushu. Nangona kunjalo, lo mgaqo awusebenzi kwizixhobo ezisebenza kakhulu. i-siliconeirabha.

"Le yingcamango engaqhelekanga. Ivundiswe ngokupheleleyo i-siliconeIrabha inesakhiwo senethiwekhi esizinzileyo kakhulu esinamacala amathathu. Xa ibekwe kubushushu, imixokelelwane yayo yeemolekyuli ihlengahlengiswa kancinci kakhulu, nto leyo ebonakala ngathi yi-'linear shrinkage' ephantsi kakhulu, ngesiqhelo ingaphantsi kwe-1%. Okubaluleke ngakumbi, ngenxa yokunyuka kobushushu kweemolekyuli zayo, into eqhelekileyo ebonakalayo yezinto ezibonakalayo kukuba ilandela umgaqo 'wokwanda kobushushu kunye nokuncitshiswa', ibonisa ukwanda okuncinci kobushushu endaweni yokuncitshiswa.

二．I-Coefficient of Thermal Expansion yiSibonakaliso esiPhambili

Ingxelo iphawula ukuba uphawu oluphambili lokuzinza kobukhulu bezinto phezu kobushushu yi-coefficient of thermal expansion (CTE) yayo. i-siliconeIrabha idla ngokuba ne-CTE ekuluhlu lwe-200-300 μm/m·°C—iphezulu kuneentsimbi kodwa iphantsi kakhulu kuneeplastiki ezininzi eziqhelekileyo kunye neerabha. Oku kuthetha ukuba utshintsho olufana nolwenziwe phantsi kotshintsho olufanayo lobushushu luncinci kakhulu kwaye lulawuleka. Yemihla ngemihla i-siliconeizitya zokupheka, iimold zokubhaka, izixhobo ze-elektroniki, kunye nezinye izinto, olu tshintsho luncinci alubonakali lula kwaye alunampembelelo ekusebenzeni.

Uzinzo luvela ekuchaseni ubushushu obuhle kakhulu

Uzinzo olunemilinganiselo i-siliconeekugqibeleni irabha ivela ekumelaneni kwayo kakuhle namaqondo obushushu aphezulu naphantsi. i-siliconeimveliso yerabha inomlinganiselo wobushushu obusebenzayo oqala kwi -60°C ukuya ngaphezulu kwama-200°C. Ngaphakathi kolu luhlu, igcina ukuthamba kwayo kunye neempawu zayo zomzimba, kwaye ayizukutshintsha okanye inciphe ngokusisigxina ngenxa yemijikelo ephindaphindwayo yobushushu nokubanda. Ingxaki akufuneki ibe kukuncipha, kodwa endaweni yoko ibe kukwaluphala kobushushu, ukuqhekeka, okanye ukubola kumaqondo obushushu aphezulu kakhulu (ngaphaya komda wayo wokunyamezela)."

Izicelo zeShishini: Ukusuka "kwi-Passive Adaptation" ukuya "kwi-Active Use" yoLwandiso lweThermal

1. Ukwenziwa kweMveliso eDibeneyo: I-silicone I-Rubber Coii-re molds zibonelela ngokulingana koxinzelelo ngokwandiswa kobushushu ngexesha lokubumba iinxalenye ze-carbon fiber, zithatha indawo yee-autoclaves zemveli kwaye zinciphisa iindleko zezixhobo ngama-50%.

2. Ukupholisa nge-elektroniki: Ukuqhuba ubushushu i-siliconeIrabha (i-CTE ye-0.5x10-4/°C kuphela) isetyenziselwa ukukhupha ubushushu kwiitships ze-5G base station, ukuqinisekisa ukuthembeka kwexesha elide kumaqondo obushushu aphezulu.

3. Iindawo Ezinzima Kakhulu: I-siliconeIzitywino zerabha ezimelana nobushushu obuphakathi kwe -60°C ukuya kwi 300°C zimelana nokukhanya kwizixhobo zesikhululo samandla enyukliya ngaphandle kokuguquka.

V. Isiphelo

"Ukuziphatha kokuguquguquka kobushushu i-siliconeIrabha ixhomekeke kuxinano lwayo lwe-crosslink kunye nenkqubo yokuzalisa. Ngokuyila iimolekyuli, sifikelele ekukhuleni kobushushu obulawulekayo, obunokuba namandla amakhulu kwizicelo ezizayo ezifana nokuvala iipakethe zebhetri zezithuthi zamandla amatsha." I-siliconeIimpawu zokwandisa ubushushu zerabha azinasiphako, kodwa zibonakalisa ukuthamba kwayo okuphezulu kunye nokuzinza. Ngokuhambela phambili kwitekhnoloji yokuguqula, le nto isuka ekubeni "ibe buthathaka kubushushu" ukuya ekubeni "ilungelelanise ubushushu," inika amathuba amakhulu okuvelisa izinto eziphezulu.
