I-Umbrella vs. I-Bulletproof Vest: Ukucacisa i-Rubber Siblings kubomi bakho bemihla ngemihla

Isiqendu Sokukhokela

Ukusuka kwiinjini zemoto ukuya kwiiglavu zasekhitshini, iindidi ezimbini zerabha—i-NBR kunye ne-HNBR—zisebenza ngokuzolileyo emva kwemifanekiso. Nangona zivakala zifana, iyantlukwano yazo ifana nqwa neambrela xa ithelekiswa nevest engenambumbulu. Nantsi indlela aba "bantakwethu berabha" babumba ngayo yonke into ukusuka kumenzi wekofu wasekuseni ukuya kwiirigi zokomba enzulu elwandle.

1. IRubber Family Tree: Dibana namawele

NBR: IQhawe leMihla le
Cinga nge-NBR njengeambrela yakho ethembekileyo. Yenziwe ngebutadiene (icandelo eliguquguqukayo elisuka kwipetroleum) kunye ne-acrylonitrile (indlu yamandla ekwazi ukumelana ne-oyile), iyafikeleleka kwaye ithembekile-de kube iimeko ezinzima.

• Apho Uza Kuyifumana khona: Iilitha zamavili ebhayisekile, iiglavu ezilahlwayo, kunye neebhutsi zemvula ezingabizi kakhulu.

• Indawo ebuthathaka: Iintanda phantsi kokuvela elangeni ixesha elide okanye amaqondo obushushu angaphezu kwe-120°C (cinga itshokolethi enyibilikisiweyo).

HNBR: Uphuculo olungenakonakala
I-HNBR ngumzala we-NBR wobugcisa obuphezulu. Izazinzulu “zomeleza” iimolekyuli zayo zisebenzisa ihydrogen, zijika “amaqhina” aethe-ethe abe ngamaqhina angaqhawukiyo.

• Amandla Amandla: Isinda kwi-150 ° C kubushushu kwaye imelana nokwaluphala njenge-sunscreen.

• Iindleko: I-3-5x i-pricier ngenxa ye-platinum-catalyzed "alchemy" ngexesha lemveliso.

Ufaniso olungundoqo:
Ukuba i-NBR yintsimbi yomqala enamaqhina abuthathaka, i-HNBR iwelda ezo ziqhaga zivaliwe-iyenza yomelele ngokwaneleyo kwiinjini zeemoto kunye nohambo lwase-Arctic.

2. Iimvavanyo ezigqithisileyo: Ubushushu, Ukubanda, kunye nexesha lokuphila

Iimfazwe Zobushushu

• I-NBR: Ayiphumelelanga kwi-120 ° C (njenge-ambrela yefloppy kwisiphango).

• I-HNBR: Ikhula kakuhle kwi-150°C (ikhuselo elikhusela ubushushu kwiindawo zenjini).

Umzekelo weLizwe lokwenyani:
Iimoto zasehlotyeni zangaphakathi zibetha i-70 ° C-iimathi zerabha exabiso liphantsi zijika zincangathi, ngelixa i-HNBR ihlala yomelele.

Ukuqina Ubuso-Off

• NBR: Iintanda emva kweminyaka emi-3–5 ngaphandle.

• I-HNBR: Ihlala ngaphezulu kweshumi leminyaka, nakwindawo ezinobunzima be-UV.

Uvavanyo lwe-DIY:
Bopha zombini iirabha kwi-balcony railing. Emva konyaka, i-NBR iya kuqhekeka; I-HNBR ihlala yolula.

3. Ifihliwe kwindawo ecacileyo: iindima zabo eziyimfihlo

NBR's Yonke imihla Domains

• Ikhitshi: Iiglavu zokubhaka ezinganyangekiyo kwi-oyile.

• Ezothutho: Imibhobho yeoli yesithuthuthu, iilitha zamavili ebhayisekile.

• Ukhathalelo lwempilo: Iiglavu ezilahlwayo zitshiphu (kodwa hayi iikhemikhali ezirhabaxa).

IMishini ye-HNBR ePhakamileyo

• Umzi-mveliso we-Auto: Imibhobho ye-Turbocharger, itywina leenjini kwiimoto zodidi.

• Imeko-bume egqithisileyo: Iigaskithi zokomba enzulu elwandle, imithungo yesuti yokutyibiliza.

• Ubuchwephesha bexesha elizayo: Izikhuselo zeebhetri zemoto zombane.

Ubusazi?
Injini yemoto yodidi inokuba inamalungu angama-5+ e-HNBR—kodwa uninzi lwabaqhubi abaqapheli!

4. Kutheni i-HNBR ixabisa i-Fortune

I "Alchemy" emva kwayo

Ukwenza i-HNBR ayikuko nje ukuxuba izithako-luxinzelelo oluphezulu, inkqubo yeplatinam-catalyzed. I-catalyst iyodwa idla i-30% yeendleko.

I-Eco Paradox

Ukuvelisa i-HNBR kukhupha kabini i-CO₂ ye-NBR. Kodwa ubomi bayo obude buthetha ukutshintshwa okumbalwa, okwenza kube luhlaza ngokuhamba kwexesha-njengengubo yasebusika ehlala ixesha elide ngokuchasene nefashoni ekhawulezayo.

5. Ukukhetha Ngobulumko: Isikhokelo soMthengi

Kukhethwa nini i-NBR

• Ukulungiswa kwexesha elifutshane (umzekelo, izitywina zexeshana).

• Iindawo ezibandayo (iigasthi zocango lwefriji).

• Izinto zebhajethi (iibhutsi zemvula zabantwana).

Kuza kuchithwa nini kwi-HNBR

• Izixhobo ezitshisa kakhulu (i-rice cooker seals).

• Izixhobo zokhuseleko ezibalulekileyo (izihlanganisi zezixhobo zelebhu).

• Utyalo-mali lwexesha elide (iinxalenye zemoto yeprimiyamu).

Ingcebiso yePro:
Uluhlu olukwi-Intanethi luqhayisa “nge-150°C ukuxhathisa” okanye “iwaranti yeminyaka eli-10” kusenokwenzeka ukuba isebenzisa i-HNBR—amaxabiso ahlolisisiweyo ukunqanda ubuqhophololo!

6. Ikamva: Ngaba Irabha Enye Iza Kuzilawula Zonke?

Ngelixa i-HNBR ilawula imimandla yobuchwepheshe obuphezulu, i-NBR ayizukuphela. Izazinzulu zezi:

• Ukomeleza ubomi be-NBR kunye ne-antioxidants.

• Ukwenza i-HNBR eco-friendly eco-friendly from corn starch.

Uqikelelo lwasendle:
"Irabha engangenwa bullet" esekwe kwitapile ngenye imini inokukhusela iirovers zikaMars-kunye nomenzi wakho wekofu.

Ukuthathwa kokugqibela

Kwixesha elizayo xa ubona imveliso yerabha, buza: “Ngaba le yiambrela okanye ivesti ekhusela iimbumbulu?” Ukukhuphisana kwabo okuthe cwaka kugcina ihlabathi lethu libaleka-ukusuka kwiiglavu zevenkile yegrosari ukuya kwizitishi zesikhululo sasemajukujukwini.
