Ilifa kunye nemingeni yeNylon-66

Ngomhla wama-28 kuFebruwari, ngo-1935, impumelelo enkulu kwisayensi yezinto yenzeka xa isazinzulu saseMelika uWallace Hume Carothers waphumelela ukuvelisa iNylon-66, i-polyamide eneempawu ezimangalisayo. Ngenxa yeqondo layo eliphezulu lokunyibilika elingama-263°C, ukumelana okungaqhelekanga nezinyibilikisi eziqhelekileyo, kunye nembonakalo efana neyesilika, le polymer intsha yamisela umgangatho omtsha wehlabathi wokuqina kunye namandla efayibha. Yayingengomsebenzi ubalulekileyo kwishishini lempahla; yayilinyathelo elibalulekileyo ekuphuhlisweni kwekhemistri yepolymer.

Sijonge phambili namhlanje, kwaye iNylon-66 isaqhubeka nokuba yinto ebalulekileyo kumashishini asebenza kakuhle njengempahla yelaphu, iimoto, izixhobo ze-elektroniki, kunye neengcingo kunye neentambo. Nangona kunjalo, njengoko iimfuno zokusebenza zisanda, ukucubungula i-PA66 kuveza imiqobo yobuchwephesha eqhubekayo abavelisi abajongene nayo imihla ngemihla.

Ukucubungula "Amanqaku Entlungu" e-PA66
Nangona i-PA66 ixatyiswa ngenxa yokuqina kwayo, ulwakhiwo lwayo lwemolekyuli lukhokelela kwimiqobo emininzi yokucubungula:

• Ukuhamba Kakubi Kokunyibilika kunye Noxinzelelo Oluphezulu Lokuphuma: Ubuninzi be-PA66 melt buthintela ukugeleza kwamanzi, nto leyo ekhokelela ekusetyenzisweni kwamandla okwandileyo, ukuguguleka kwezixhobo, kunye nesantya esilinganiselweyo semveliso.

• Iphupha Elibi “leFayibha yeGlasi eQokeleyo”: Ukuze kufumaneke amandla agqithisileyo olwakhiwo, i-PA66 idla ngokuqiniswa ngeFayibha yeGlasi (GF) engama-30%–50%. Ngenxa yokuba amazinga okuhamba kwefayibha yeglasi kunye ne-matrix yenylon awahambelani, iifayibha zihlala zifudukela kumphezulu. Oku kubangela “iFayibha eQokeleyo”—imisonto emhlophe engathandekiyo, erhabaxa eyonakalisa ukugqitywa komphezulu kwaye idale iindawo zoxinzelelo, nto leyo ebeka emngciphekweni ulwakhiwo lwenxalenye.

• Iziphene zomphezulu kunye nokulahleka kokukhanya okucacileyo: Uxinzelelo oluphezulu lokucubungula lunokubangela "ukuqhekeka kwe-sharkskin" (ukuqhekeka okunyibilikayo) okanye ukwakheka kombala oqinileyo, okubangela uburhabaxa bomphezulu kunye nokuphazamisa ukucaca kokukhanya kwee-polyamides ezicacileyo. Oku kuyingxaki ngakumbi kwizicelo apho umgangatho wokubonakala ubaluleke kakhulu, njengakwiingubo zocingo eziphezulu kunye neentambo.

Ezi ndawo zinzima zokucubungula azichaphazeli nje kuphela umgangatho wemveliso kodwa zikwakhokelela kumazinga aphezulu enkunkuma, imijikelo yemveliso emide, kunye neendleko zokusebenza ezinyukileyo—ekugqibeleni zichaphazela umvuzo wakho.

Njengovulindlela kwiukuguqulwa kwepolymer esekwe kwisilicone,I-SILIKE ibonelela ngazo zonke iintlobo zezongezo ze-siloxane ezisebenza kakuhle, ii-silicone masterbatches, izongezo ze-polymer, kunye netekhnoloji yokuphucula umphezulu eziphucula ukuqina, ukuqhubekeka, kunye nozinzo lweenkqubo ze-Nylon-66, i-Polyamide 66 GF.

Izongezo zeSilicone zeSILIKE: Isisombululo Esisebenzayo Sokucubungula i-PA66
I-SILIKE inikezela ngepotifoliyo yezisombululo ezikhethekileyo ezenzelwe ukuguqula ukusebenziseka kweenkqubo ze-polyamide:

1. I-SILIKE Silicone Masterbatch
Isetyenziswa kakhulu njengesithambisi esisebenzayo sokucubungula kunye nesongezo sokukhulula, i-SILIKEI-Silicone Masterbatch LYSI-307kwayeI-Silixone Masterbatch LYSI-407zilungele iinkqubo ze-resin ezihambelana ne-PA6. Ziphucula iipropati zokucubungula kunye nomgangatho womphezulu ngokubonelela:

• Ukuphucula ukuhamba kwe-resin kunye nokuzaliswa/ukukhululwa kwesikhunta ngokulula.

• I-torque ye-extruder enciphileyo kunye ne-coefficient ephantsi ye-friction (COF).

• Ukumelana okukhulu kweentlungu nokukrweleka.

Inzuzo ephambili: Ukwenziwa ngcono kwee-polyamide thermal break strips, okuvumela ukuba imveliso ikhawuleze kwaye ikhuphe isikhunta ngaphandle komthungo.

Imibuzo Ebuzwa Rhoqo: Ukuphucula i-PA66 kunye ne-Glass Fiber Polyamide Processing
Umbuzo 1: Ndingayisusa njani "iFloating Fiber" (imicu emhlophe) kumphezulu weGlass Fiber eqinisiweyo yePA66?
A: “I-Floating Fiber” yenzeka xa amazinga okuhamba kwe-nylon matrix kunye neefayibha zeglasi engaguquguqukiyo. Ukusebenzisa i-SILIKE SILIMER 5150, isongezo se-silicone wax esilungisiweyo, kuphucula ukuhambelana kwe-interfacial kunye nokulinganisela ukuhamba. Oku kuqinisekisa ukuba i-resin ye-PA66 igubungela ngokufanelekileyo iifayibha (30%–50% GF), nto leyo ephumela ekugqityweni komphezulu okugudileyo, okufanayo ngaphandle kwemigca yefayibha ebonakalayo.

Umbuzo 2: Yeyiphi indlela engcono yokunciphisa uxinzelelo lwe-extrusion kunye nokuphucula ukuhamba kwe-melt kwimveliso ye-PA66?
A: I-melt viscosity ephezulu kwi-PA66 idla ngokukhokelela kuxinzelelo oluphezulu lwe-extrusion kunye nokuguguleka kwezixhobo. I-SILIKE Silicone Masterbatch LYSI-407 kunye ne-SILIMER 5150 zisebenza njengezithambisi zangaphakathi nezangaphandle ezisebenzayo kakhulu. Zinciphisa kakhulu i-melt viscosity kunye ne-extruder torque, zivumela amaqondo obushushu aphantsi okucubungula, ukusetyenziswa kwamandla okunciphileyo, kunye nokuveliswa okuphezulu.

Umbuzo 3: Ngaba izongezo zokucubungula zingawuphucula umgangatho womphezulu we-PA66 ngaphandle kokulahlekelwa kukukhanya okubonakalayo?
A: Ewe. Nangona iiwax zemveli zinokubangela amafu okanye "umkhenkce," i-SILIKE SILIMER 5150 yenzelwe ngokukodwa iipolyamides ezicacileyo. Inciphisa iziphene zomphezulu ezifana "ne-sharkskin" kunye nokwakheka kombala odayileyo ngelixa igcina ukucaca okubalulekileyo kokukhanya kunye nokucaca okufunekayo kwiingubo zentambo eziphezulu kunye neentambo kunye nezixhobo ze-PA66 ezikumgangatho ophezulu.
