Iindaba - Susa ukuPeleka kweTPU kwiNylon Overmolding ngeSi-TPV, Izinto ezifanelekileyo ezithambileyo nezithuthuzelayo ezilungele ulusu kwiNylon Overmolding

Susa isisombululo se-Overmolding se-Nylon Si-TPV 3525-65A esiqinileyo

Kutheni i-Soft Overmolding kwi-Nylon ibaluleke kangaka?

I-nylon, njengeplastiki yobunjineli, isetyenziswa kakhulu kwiindlela ezahlukeneyo zokusebenza ngenxa yeempawu zayo ezintle zobugcisa. Nangona kunjalo, umphezulu wayo oqinileyo uhlala ukhokelela ekubeni kungabikho mvakalelo yokuchukumisa kakuhle kunye nokukrweleka kwesikhumba ngexesha lokudibana nomntu. Ukujongana nale meko, ii-elastomers ezithambileyo ezinobunzima be-Shore ukusuka kwi-40A ukuya kwi-80A (ngesiqhelo i-60A ~ 70A) zigqunywa kwi-substrates ze-nylon, zibonelela ngokhuseleko olunobuhlobo nolusu, intuthuzelo ephuculweyo yokuchukumisa, kunye nokuguquguquka okukhulu koyilo.

Iindlela zemveli zokubopha ngokwasemzimbeni (umz., uyilo oluhambelana ne-snap-fit, ukugoba, okanye imiphezulu enemisonto) yokubopha i-nylon inengxaki yokunamathela okungaguqukiyo kunye nenkululeko yoyilo elinganiselweyo. Ngokwahlukileyo koko, ukubopha kweekhemikhali kusebenzisa i-molecule affinity, i-polarity, okanye i-hydrogen bonding phakathi kwezinto, ukuqinisekisa ukunamathela okufanayo kuyo yonke indawo kwaye kuvumela iijometri ezintsonkothileyo.

Iingxaki zokusebenzisa i-TPU kwi-Nylon Overmolding

I-Thermoplastic Polyurethane (TPU) isetyenziswa kakhulu ekubumbeni i-nylon ngenxa yokumelana nokuguguleka kwayo kunye nokulinganisela okuhle koomatshini. Ihlala ithathwa njengehambelana ne-nylon ngenxa yokuba ine-polarity efanayo. Nangona kunjalo, i-TPU idla ngokuba ne-interfacial adhesion embi, nto leyo ekhokelela ekuqhekekeni okanye ekuqhekekeni, ingakumbi kwiimeko zoxinzelelo oluphezulu okanye ezisetyenziswa ixesha elide.—ekugqibeleni kunciphisa umgangatho kunye nokusebenza kwemveliso.

Isisombululo:Ukwazisa i-Si-TPV 3525-65A, enye indlela ye-TPU, eyona elastomer ilungileyo yokwenza i-nylon overmolding

Ukujongana nemida ye-TPU, iSilike iphuhlise i-Si-TPV 3525-65A—i-silicone-thermoplastic vulcanizate elastomer egcina iipropati ezinqwenelekayo ze-TPU ngelixa iphucula kakhulu ukunamathela kwi-substrates ze-nylon.

Okuizinto ezintsha ze-thermoplastic elastomer ze-Si-TPV ezithambileyoizibonelelo:

1. Ukubopha okugqwesileyo kweekhemikhali kunye ne-PA6, i-PA12, kunye ne-PA66

2. Ihlala ixesha elide, i-interface efanayo yokugquma

3. Umphezulu othambileyo onentuthuzelo ephuculweyo yomsebenzisi

4. Ukuqina okugqwesileyo koomatshini, amanzi, ukumelana neoyile, kunye nokuguquguquka kokubanda

Ukusebenza Okugqwesileyo Kokubumba kweSi-TPV 3525-65A kwiNylon Substrates, Uphononongo Lokuthelekisa neTPU Lokuphucula Ukubopha kunye neNtlalontle Yokuthinta!

Ukuvavanya ukunamathela: Uvavanyo oluQokelelweyo oluQokelelweyo

Ukuthelekisa ukusebenza kwe-bonding, i-Si-TPV kunye ne-TPU zavavanywa kusetyenziswa inkqubo eqhelekileyo yokubumba ngaphezulu:

Ii-substrates ze-nylon (PA6) zibunjwe nge-injection, emva koko zinqunyulwe nge-diagonal kwi-45° zaza zapholishwa nge-sandpaper ye-120-grit.

Ii-substrates ezilungisiweyo ziphinde zafakwa kwiimold ukuze zigqunywe ngaphezulu phantsi kobushushu obulawulwayo kunye noxinzelelo.

Kwenziwe uvavanyo lokuxinana ukuze kuvavanywe amandla okubopha phakathi kwe-interfacial.

I-TPU vs. Si-TPV 3525-65A kwi-PA6: Iziphumo zoVavanyo lwe-Tensile Force kwi-Break kunye ne-Adhesion

Phucula uyilo lweMveliso yeNylon ngeSoft-Touch Overmolding ngeSi-TPV 3525-65A Solutions

I-Superior Bonding kwi-PA6, PA12, kunye ne-PA66, i-Si-TPV 3525-65A Ichaziwe Ukusebenza Kokuncamathela

Ukugquma kweTPU kwiisubstrates zePA:

Njengoko ubunzima be-TPU bukhula (60A ukuya kwi-90A), amandla okubopha kwi-PA6 ehla kakhulu. Kwi-90A, i-TPU ayizange ikwazi ukubopha ngokupheleleyo.

I-Si-TPV 3525-65A Overmolding, enye indlela ye-TPU yokubumba i-nylon overmolding:

Kubonise ukubopha okuqinileyo nokungaguquguqukiyo kwi-PA6. Uhlalutyo olunqamlezileyo lubonakalise ukungaphumeleli kokubambisana—i-Si-TPV yahlala inamathele kumacala omabini ojongano, nto leyo ebonisa ukubopha okuqinileyo kweekhemikhali. Ngokwahlukileyo koko, ujongano lwe-TPU lubonise intsalela encinci, nto leyo ebonisa ukunamathela okubuthathaka.

Izinto ezithambileyo zeSi-TPV 3525-65A kuzo zonke iintlobo zeeNylon Grades: Zithembekile kuzo zonke iiPA6, PA12, PA66

I-Modified Silicone Elastomer 3525-65A ikwafumene ukubopha okuqinileyo kwiintlobo ezininzi ze-nylon.

I-Non-Sticky Thermoplastic Elastomer Si-TPV 3525-65A kwi-PA12, i-overmolding ayibonisanga kwahlukana okubonakalayo ngexesha lovavanyo, iqinisekisa ukubopha okuqinileyo ngaphandle kokusilela kwe-interface.

Ii-Elastomers ze-Si-TPV ezingenazo iiplastiki3525- 65A kwi-PA66, izinto zigcine ukunamathelana okuqinileyo kunye nokuqina kwesakhiwo phantsi komthwalo.

(Qaphela: Zonke iimpawu zokuqina kolwandle kunye neenkqubo zovavanyo ziyahambelana nemigangatho yamazwe ngamazwe yovavanyo lwe-elastomer kunye nokunamathela.)
