Pi-olyurethane potting compound yombane evela eTshayina i-polyurethane potting compound abavelisi

Polyurethane encapsulating kunye iikhompawundi potting zineenzuzo ezininzi, ngakumbi xa unyango olukhawulezayo lufuneka kumaqondo obushushu aphantsi. Esi sisombululo singcono xa kuthelekiswa neenkqubo ze-epoxy. Nge-polyurethanes, kukho ukumelana nokuqhekeka okungcono kunye nokuguquguquka. Kukwakho ukuncamathela okungcono kwezinye iisubstrates ezinje ngee-composites kunye neeplastiki.

Uninzi lwee-polyurethanes zisebenzisa imathiriyeli ehlaziywayo ekrwada. Oku kuthetha ukuba akukho monakalo omncinci kumthengi wokugqibela. Olu lolona khetho lufanelekileyo kwizicelo ezahlukeneyo ze-elektroniki kunye ne-tech Mount tech. Kwakhona ukhetho olufanelekileyo kwiimeko apho ukuxhathisa kwebhayisikile ye-thermal kuyadingeka. Xa i-polyurethane ine-CTE ephantsi, ithetha ukuba iguquguquka nakwiqondo lokushisa eliphantsi kakhulu.

Enye yezona zinto zilungileyo malunga nale khompawundi kukuba ikhemistri inokuphindaphinda ngokulula iintlobo ezahlukeneyo zobunzima kwiimveliso ezahlukeneyo. Oku kuquka:

• Iikhompawundi ze-LEDM
• irabha
• ithermoplastics
• iglasi

Inkqubo yamacandelo amabini isetyenziswa ngokubanzi kwi-potting kunye ne-encapsulation yamacandelo e-elektroniki. Ineempawu eziguquguqukayo ezifana nokuhamba kakuhle kwe-thermal, ukugquma kombane, ukusebenza kwe-dielectric, i-viscosity eguquguqukayo, kunye ne-durometer ephantsi.

Kutheni ukhetha i-polyurethane?

Iirethane okanye ipolyurethane resins zenzeka ukuba yirabha okanye elastomeric xa zithe zanyangwa. Kufuneka uzikhethe ngenxa yokuba:

• Lukhetho olukhethwayo ukuba iinxalenye zeembiza zineenxalenye ezinikezelweyo.
• Enye into engalunganga kukuba i-polyurethane ayinakusetyenziswa kwizicelo ezinobushushu obungaphezulu kwe-125 degrees Celsius. Nangona kunjalo, le khompawundi yeyona nto ilungileyo xa ukhangela ulungelelwaniso phakathi kokuguquguquka kunye namandla omatshini.
• Kuhlala kulula ukulungisa isantya sokunyanga ngenkqubo enjalo kunye nobomi obusebenzisekayo. Ixesha lejeli liyakwazi ukulungiswa ngokulula ukuhlangabezana neemfuno zomthengi. Oku kukhokelela kwixesha elikhawulezayo lokucubungula kunye nomsebenzi omncinci oqhubekayo.
• Iikhompawundi zePolyurethane zisetyenziselwa izicelo apho amaxesha okusebenza amafutshane afunekayo ukuze kufumaneke awona mazinga alungileyo emveliso. Kwakhona lukhetho olulungileyo lwezicelo ze-cryogenic kunye nokutywinwa kweendibano.
• I-Polyurethane nayo ixabisa kakhulu. Abavelisi abagqwesileyo banesatifikethi esifanelekileyo kwaye bahlangabezana nemigangatho eyahlukeneyo yehlabathi.

Ukukhetha i-polyurethane kufuneka isekelwe kumthamo wokumelana owufunayo kwiindawo ezithile kunye neendleko. Ezi zixhobo zinokunika iipropati ezahlukeneyo kwaye ziyindlela engcono kakhulu kwi-silicone.

Ukufumana eyona mveliso igqwesileyo

Kukho abadlali abaninzi kwimarike yokukhangela i-polyurethane iikhompawundi potting. Ukusebenza nathi kwizinto ezinzulu kuqinisekisa ukuba ufumana izandla zakho kwiimveliso ezikumgangatho ophezulu. Zininzi izibonelelo ezinxulumene nokusebenza nenkampani esekwe kakuhle. Inkampani enjalo sele iziqonda iimfuno ezikhoyo kwimarike. Ngumenzi kuphela onokukukhokela ekukhetheni kwakho, eqinisekisa ukuba ufumana kuphela ezona ziphumo zilungileyo.

Enye into ekufuneka siyiqaphele ngathi kukuba sigxile kuphando nophuhliso. Ngale ndlela, sinokuqhubeka siphucula iinkonzo zethu kunye neemveliso. Sikwajongana nezisombululo ezenziweyo. Siyaqonda ukuba ezinye iiprojekthi zikwinqanaba lazo kwaye zinokufuna ingqwalasela eyodwa ukuze izinto zihambe njengoko kufanele. Sinoluhlu olubanzi lweemveliso ze-polyurethane ukukhetha kuzo. Eyona nto ibalulekileyo kukufumana imveliso eya kuzisa eyona ilungileyo kwisicelo sakho.
